The new version supports two features that are required by upcoming
changes in the driver:
* Querying of new resources allowing port split into two ports on
Spectrum-2 systems
* Querying of number of gearboxes on supported systems such as SN3800

TIPC link can temporarily fall into "half-establish" that only one of
the link endpoints is ESTABLISHED and starts to send traffic, PROTOCOL
messages, whereas the other link endpoint is not up (e.g. immediately
when the endpoint receives ACTIVATE_MSG, the network interface goes
down...).
This is a normal situation and will be settled because the link
endpoint will be eventually brought down after the link tolerance time.
However, the situation will become worse when the second link is
established before the first link endpoint goes down,
For example:
1. Both links <1A-2A>, <1B-2B> down
2. Link endpoint 2A up, but 1A still down (e.g. due to network
disturbance, wrong session, etc.)
3. Link <1B-2B> up
4. Link endpoint 2A down (e.g. due to link tolerance timeout)
5. Node B starts failover onto link <1B-2B>
==> Node A does never start link failover.
When the "half-failover" situation happens, two consequences have been
observed:
a) Peer link/node gets stuck in FAILINGOVER state;
b) Traffic or user messages that peer node is trying to failover onto
the second link can be partially or completely dropped by this node.
The consequence a) was actually solved by commit c140eb166d68 ("tipc:
fix failover problem"), but that commit didn't cover the b). It's due
to the fact that the tunnel link endpoint has never been prepared for a
failover, so the 'l->drop_point' (and the other data...) is not set
correctly. When a TUNNEL_MSG from peer node arrives on the link,
depending on the inner message's seqno and the current 'l->drop_point'
value, the message can be dropped (- treated as a duplicate message) or
processed.
At this early stage, the traffic messages from peer are likely to be
NAME_DISTRIBUTORs, this means some name table entries will be missed on
the node forever!
The commit resolves the issue by starting the FAILOVER process on this
node as well. Another benefit from this solution is that we ensure the
link will not be re-established until the failover ends.

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.

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(*s) + s->nkeys*sizeof(struct tc_u32_key)
with:
struct_size(s, keys, s->nkeys)
This code was detected with the help of Coccinelle.

Although devlink health report does a nice job on reporting TX
timeout and other NIC errors, unfortunately it requires drivers
to support it but currently only mlx5 has implemented it.
Before other drivers could catch up, it is useful to have a
generic tracepoint to monitor this kind of TX timeout. We have
been suffering TX timeout with different drivers, we plan to
start to monitor it with rasdaemon which just needs a new tracepoint.
Sample output:
ksoftirqd/1-16 [001] ..s2 144.043173: net_dev_xmit_timeout: dev=ens3 driver=e1000 queue=0

This patch adds support for FEC encoding control, user can change
FEC mode by command ethtool --set-fec, and get FEC mode by command
ethtool --show-fec. The fec capability is changed follow the port
speed. If autoneg on, the user configure fec mode will be overwritten
by autoneg result.

Previously, our driver only supports phydev to autoneg or change
port speed. This patch adds support for fibre port, driver gets
media speed capability and autoneg capability from firmware. If
the media supports multiple speeds, user can change port speed
with command "ethtool -s <devname> speed xxxx autoneg off duplex
full". If autoneg on, the user configuration may be overwritten
by the autoneg result.

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.

If the NO_CPU strap is set, the switch starts in 'dumb hub' mode, with
all ports enable. Ports which are then actively used are reconfigured
as required when the driver starts. However unused ports are left
alone. Change this to disable them, and turn off any SERDES
interface. This could save some power and so reduce the temperature a
bit.

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.

Printing each devices PCI vendor and device ID has the advantage of
easily revealing what hardware we're dealing with exactly. It's no
longer necessary to match the PCI bus information to the lspci output.
Helps with bug reports where no lspci output is available.

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.
