When splitting a port, different local ports need to be mapped on different
systems. For example:
SN3700 (local_ports_in_2x=2):
* Without split:
front panel 1 --> local port 1
front panel 2 --> local port 5
* Split to 2:
front panel 1s0 --> local port 1
front panel 1s1 --> local port 3
front panel 2 --> local port 5
SN3800 (local_ports_in_2x=1):
* Without split:
front panel 1 --> local port 1
front panel 2 --> local port 3
* Split to 2:
front panel 1s0 --> local port 1
front panel 1s1 --> local port 2
front panel 2 --> local port 3
The local_ports_in_{1x, 2x} resources provide the offsets from the base
local ports according to which the new local ports can be calculated.

I got an interesting report [0] that after resuming from hibernation
the link has 100Mbps instead of 1Gbps. Reason is that another OS has
been used whilst Linux was hibernated. And this OS speeds down the link
due to WoL. Therefore, when resuming, we shouldn't expect that what
the PHY advertises is what it did when hibernating.
Easiest way to do this is removing state PHY_RESUMING. Instead always
go via PHY_UP that configures PHY advertisement.

When probing the phy device we set sym and asym pause in the "supported"
bitmap (unless the PHY tells us otherwise). However we don't know yet
whether the MAC supports pause. Simply copying phy->supported to
phy->advertising will trigger advertising pause, and that's not
what we want. Therefore add phy_advertise_supported() that copies all
modes but doesn't touch the pause bits.
In phy_support_(a)sym_pause we shouldn't set any bits in the supported
bitmap because we may set a bit the PHY intentionally disabled.
Effective pause support should be the AND-combined PHY and MAC pause
capabilities. If the MAC supports everything, then it's only relevant
what the PHY supports. If MAC supports sym pause only, then we have to
clear the asym bit in phydev->supported.
Copy the pause flags only and don't touch the modes, because a driver
may have intentionally removed a mode from phydev->advertising.

100GbE Intel Wired LAN Driver Updates 2019-05-02
This series contains updates to the ice driver only.
Anirudh introduces the framework to store queue specific information in
the VSI queue contexts. This will allow future changes to update the
structure to hold queue specific information.
Akeem adds additional check so that if there is no queue to disable when
attempting to disable a queue, return a configuration error without
acquiring the lock. Fixed an issue with non-trusted VFs being able to
add more than the permitted number of VLANs.
Bruce removes unreachable code and updated the function to return void
since it would never return anything but success.
Brett provides most of the changes in the series, starting with reducing
the scope of the error variable used and improved the debug message if
we fail to configure the receive queue. Updates the driver to use a
macro instead of using the same 'for' loop throughout the driver which
helps with readability. Fixed an issue where users were led to believe
they could set rx-usecs-high value, yet the changes to this value would
not stick because it was not yet implemented to allow changes to this
value, so implement the missing code to change the value. Found we had
unnecessary wait when disabling queues, so remove it. I,proved a
wasteful addition operation in our hot path by adding a member to the
ice_q_vector structure and the necessary changes to use the member which
stores the calculated vector hardware index. Refactored the link event
flow to make it cleaner and more clear.
Maciej updates the array index when stopping transmit rings, so that
process every ring the VSI, not just the rings in a given transmit
class.
Paul adds support for setting 52 byte RSS hash keys.
Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register,
since the interrupt handlers will handle resetting the bit, if
necessary.
Tony adds a missing PHY type, which was causing warning message about an
unrecognized PHY.

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, replace code of the following form:
sizeof(*tx_msg) + le16_to_cpu(tx_msg->num_pls) * sizeof(tx_msg->pld[0]);
with:
struct_size(tx_msg, pld, le16_to_cpu(tx_msg->num_pls));
This code was detected with the help of Coccinelle.

Previously, we can only identify copper and fiber type, the
supported link modes of port information are always showing
SR type. This patch adds support for multiple media types,
include SR, LR CR, KR. Driver needs to query the media type
from firmware periodicly, and updates the port information.
The new port information looks like this:
Settings for eth0:
Supported ports: [ FIBRE ]
Supported link modes: 25000baseCR/Full
25000baseSR/Full
1000baseX/Full
10000baseCR/Full
10000baseSR/Full
10000baseLR/Full
Supported pause frame use: Symmetric
Supports auto-negotiation: No
Supported FEC modes: None BaseR
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Advertised FEC modes: Not reported
Speed: 10000Mb/s
Duplex: Full
Port: FIBRE
PHYAD: 0
Transceiver: internal
Auto-negotiation: off
Current message level: 0x00000036 (54)
probe link ifdown ifup
Link detected: yes
In order to be compatible with old firmware which only support
sfp speed, we remained using the same query command, and kept
the former logic.

ipheth_carrier_set() is called from two locations. In
ipheth_carrier_check_work(), its parameter 'dev' is set with
container_of(work, ...) and can not be NULL. In ipheth_open(),
dev is extracted from netdev_priv(net) and dereferenced before
the call to ipheth_carrier_set(). The NULL pointer check of dev
in ipheth_carrier_set() is therefore unnecessary and can be removed.

This patch introduces "recovery mode" to the i40e driver. It is
part of a new Any2Any idea of upgrading the firmware. In this
approach, it is required for the driver to have support for
"transition firmware", that is used for migrating from structured
to flat firmware image. In this new, very basic mode, i40e driver
must be able to handle particular IOCTL calls from the NVM Update
Tool and run a small set of AQ commands.
These additional AQ commands are part of the interface used by
the NVMUpdate tool. The NVMUpdate tool contains all of the
necessary logic to reference these new AQ commands. The end user
experience remains the same, they are using the NVMUpdate tool to
update the NVM contents.

A refactor of the i40e_vc_config_promiscuous_mode_msg function moved
the check for un-trusted VF into another function. We have to lie to
an un-trusted VF that its request to set promiscuous mode is
successful even when it is not because we don't want the VF to find
out its trust status this way. With the refactor, we were running into
a case where even though we were not setting promiscuous mode for an
un-trusted VF, we still printed a misleading message that it was
successful.
This patch fixes that by ensuring that a success message is printed
on the host side only when the promiscuous mode change has been
successful.

The function i40e_validate_cloud_filter checks that the destination and
source port numbers are valid by attempting to ensure that the number is
non-zero and no larger than 0xFFFF. However, the types for the dst_port
and src_port variable are __be16 which by definition cannot be larger
than 0xFFFF
Since these values cannot be larger than 2 bytes, the check to see if
they exceed 0xFFFF is meaningless.
One might consider these checks as some sort of defensive coding, in
case the type was later changed. However, these checks also byte-swap
the value before comparison using be16_to_cpu, which will truncate the
values to 16bits anyways. Additionally, changing the type would require
updating the opcodes to support new data layout of these virtchnl
commands.
Remove the check to silence the -Wtype-limits warning that was added to
GCC 8.

Ethernet flow control:
The switch MAC does not consume, nor does it emit pause frames. It
simply forwards them as any other Ethernet frame (and since the DMAC is,
per IEEE spec, 01-80-C2-00-00-01, it means they are filtered as
link-local traffic and forwarded to the CPU, which can't do anything
useful with them).
Duplex:
There is no duplex setting in the SJA1105 MAC. It is known to forward
traffic at line rate on the same port in both directions. Therefore it
must be that it only supports full duplex.

Resetting the switch at runtime is currently done while changing the
vlan_filtering setting (due to the required TPID change).
But reset is asynchronous with packet egress, and the switch core will
not wait for egress to finish before carrying on with the reset
operation.
As a result, a connected PHY such as the BCM5464 would see an
unterminated Ethernet frame and start to jabber (repeat the last seen
Ethernet symbols - jabber is by definition an oversized Ethernet frame
with bad FCS). This behavior is strange in itself, but it also causes
the MACs of some link partners (such as the FRDM-LS1012A) to completely
lock up.
So as a remedy for this situation, when switch reset is required, simply
inhibit Tx on all ports, and wait for the necessary time for the
eventual one frame left in the egress queue (not even the Tx inhibit
command is instantaneous) to be flushed.

If STP is active, this setting is applied on bridged ports each time an
Ethernet link is established (topology changes).
Since the setting is global to the switch and a reset is required to
change it, resets are prevented if the new callback does not change the
value that the hardware already is programmed for.

VLAN filtering cannot be properly disabled in SJA1105. So in order to
emulate the "no VLAN awareness" behavior (not dropping traffic that is
tagged with a VID that isn't configured on the port), we need to hack
another switch feature: programmable TPID (which is 0x8100 for 802.1Q).
We are reprogramming the TPID to a bogus value which leaves the switch
thinking that all traffic is untagged, and therefore accepts it.
Under a vlan_filtering bridge, the proper TPID of ETH_P_8021Q is
installed again, and the switch starts identifying 802.1Q-tagged
traffic.

Documentation/devicetree/bindings/net/ethernet.txt is confusing because
it says what the MAC should not do, but not what it *should* do:
* "rgmii-rxid" (RGMII with internal RX delay provided by the PHY, the MAC
should not add an RX delay in this case)
The gap in semantics is threefold:
1. Is it illegal for the MAC to apply the Rx internal delay by itself,
and simplify the phy_mode (mask off "rgmii-rxid" into "rgmii") before
passing it to of_phy_connect? The documentation would suggest yes.
1. For "rgmii-rxid", while the situation with the Rx clock skew is more
or less clear (needs to be added by the PHY), what should the MAC
driver do about the Tx delays? Is it an implicit wild card for the
MAC to apply delays in the Tx direction if it can? What if those were
already added as serpentine PCB traces, how could that be made more
obvious through DT bindings so that the MAC doesn't attempt to add
them twice and again potentially break the link?
3. If the interface is a fixed-link and therefore the PHY object is
fixed (a purely software entity that obviously cannot add clock
skew), what is the meaning of the above property?
So an interpretation of the RGMII bindings was chosen that hopefully
does not contradict their intention but also makes them more applied.
The SJA1105 driver understands to act upon "rgmii-*id" phy-mode bindings
if the port is in the PHY role (either explicitly, or if it is a
fixed-link). Otherwise it always passes the duty of setting up delays to
the PHY driver.
The error behavior that this patch adds is required on SJA1105E/T where
the MAC really cannot apply internal delays. If the other end of the
fixed-link cannot apply RGMII delays either (this would be specified
through its own DT bindings), then the situation requires PCB delays.
For SJA1105P/Q/R/S, this is however hardware supported and the error is
thus only temporary. I created a stub function pointer for configuring
delays per-port on RXC and TXC, and will implement it when I have access
to a board with this hardware setup.
Meanwhile do not allow the user to select an invalid configuration.

Currently only the (more difficult) first generation E/T series is

On P/Q/R/S, the TCAM should be fully associative. However the SPI

This structure was used intensively for machine specific values
when DT was not used. Since the removal of AVR32 from the kernel,
this structure is only used for passing clocks from PCI macb wrapper, all
other fields being 0.
All other known platforms use DT.
Remove the leftovers but make sure that PCI macb still works as
expected by using default values:
- phydev->irq is set to PHY_POLL by mdiobus_alloc()
- mii_bus->phy_mask is cleared while allocating it
- bp->phy_interface is set to PHY_INTERFACE_MODE_MII if mode not found
in DT.
This simplifies driver probe path and particularly phy handling.

Pull PCI fixes from Bjorn Helgaas:
"I apologize for sending these so late in the cycle. We went back and
forth about how to deal with the unexpected logging of intentional
link state changes and finally decided to just config them off by
default.
PCI fixes:
- Stop ignoring "pci=disable_acs_redir" parameter (Logan Gunthorpe)
- Use shared MSI/MSI-X vector for Link Bandwidth Management (Alex
Williamson)
- Add Kconfig option for Link Bandwidth notification messages (Keith
Busch)"

e8303bb7a75c ("PCI/LINK: Report degraded links via link bandwidth
notification") added dmesg logging whenever a link changes speed or width
to a state that is considered degraded. Unfortunately, it cannot
differentiate signal integrity-related link changes from those
intentionally initiated by an endpoint driver, including drivers that may
live in userspace or VMs when making use of vfio-pci. Some GPU drivers
actively manage the link state to save power, which generates a stream of
messages like this:
vfio-pci 0000:07:00.0: 32.000 Gb/s available PCIe bandwidth, limited by 2.5 GT/s x16 link at 0000:00:02.0 (capable of 64.000 Gb/s with 5 GT/s x16 link)
Since we can't distinguish the intentional changes from the signal
integrity issues, leave the reporting turned off by default. Add a Kconfig
option to turn it on if desired.

The PHY type ICE_PHY_TYPE_LOW_25G_AUI_C2C is missing from
ice_get_settings_link_up() which is causing a warning
message for unrecognized PHY. Add the PHY type to
correctly set the settings and avoid the warning message.

Every time we want to re-enable interrupts and/or write to a register
that requires an interrupt vector's hardware index we do the following:
vsi->hw_base_vector + q_vector->v_idx
This is a wasteful operation, especially in the hot path. Fix this by
adding a u16 reg_idx member to the ice_q_vector structure and make the
necessary changes to make this work.

Runtime change of PFINT_OICR_ENA register is unnecessary.
The handlers should always clear the atomic bit for each
task as they start, because it will make sure that any late
interrupt will either 1) re-set the bit, or 2) be handled
directly in the "already running" task handler.

This patch fixes issue with non trusted VFs being able to add more than
permitted number of VLANs by adding a check in ice_vc_process_vlan_msg.
Also don't return an error in this case as the VF does not need to know
that it is not trusted.
Also rework ice_vsi_kill_vlan to use the right types.

In ice_vsi_ctrl_rx_rings() we are unnecessarily waiting for
QRX_CTRL_QENA_REQ and QRX_CTRL_QENA_STAT to be the same value prior to
disabling each Rx queue. There is no reason to do this so remove
this wait loop as we already have a wait loop after disabling/enabling
the Rx queue through the QRX_CTRL register to make sure it gets
successfully disabled/enabled.
