With the version no longer required to allocate the net device, it can
be moved to probe and the alloc_m_can_dev() function can be simplified.
Therefore, move the allocation of net device to probe and change
alloc_m_can_dev() to setup_m_can_dev().

Currently the m_can version is used to set the tx_fifo_count to 1 when
allocating the net device. However, this is redundant as a value of 1
for the tx_fifo_count needs to be provided in the bosch,mram-cfg
property of the device tree node anyway.
Therefore, remove check for version when allocating the net device.

During test transmitting using CAN-FD at high bitrates (> 2 Mbps)
would fail. Scoping the signals I noticed that only a single bit
was being transmitted and with a bit more investigation realized the
actual MCAN IP would go back to initialization mode automatically.
It appears this issue is due to the MCAN needing to use the Transmitter
Delay Compensation Mode with the correct value for the transmitter delay
compensation offset (tdco). What impacts the tdco value isn't 100% clear
but to calculate it you use an equation defined in the MCAN User's Guide.
The user guide mentions that this register needs to be set based on clock
values, secondary sample point and the data bitrate. One of the key
variables that can't automatically be determined is the secondary
sample point (ssp). This ssp is similar to the sp but is specific to this
transmitter delay compensation mode. The guidelines for configuring
ssp is rather vague but via some CAN test it appears for DRA76x that
putting the value same as data sampling point works.
The CAN-CIA's "Bit Time Requirements for CAN FD" paper presented at
the International CAN Conference 2013 indicates that this TDC mode is
only needed for data bit rates above 2.5 Mbps. Therefore, only enable
this mode when the data bit rate is above 2.5 Mbps.

Various CAN or CAN-FD IP may be able to run at a faster rate than
what the transceiver the CAN node is connected to. This can lead to
unexpected errors. However, CAN transceivers typically have fixed
limitations and provide no means to discover these limitations at
runtime. Therefore, add support for a can-transceiver node that
can be reused by other CAN peripheral drivers to determine for both
CAN and CAN-FD what the max bitrate that can be used. If the user
tries to configure CAN to pass these maximum bitrates it will throw
an error.
Also add support for reading bitrate_max via the netlink interface.

Allocating steerable UD QPs depends on having at least one IB port,
while releasing those QPs does not.
As a result, when there are only ETH ports, the IB (RoCE) driver
requests releasing a qp range whose base qp is zero, with
qp count zero.
When SR-IOV is enabled, and the VF driver is running on a VM over
a hypervisor which treats such qp release calls as errors
(rather than NOPs), we see lines in the VM message log like:
mlx4_core 0002:00:02.0: Failed to release qp range base:0 cnt:0
Fix this by adding a check for a zero count in mlx4_release_qp_range()
(which thus treats releasing 0 qps as a nop), and eliminating the
check for device managed flow steering when releasing steerable UD QPs.
(Freeing ib_uc_qpns_bitmap unconditionally is also OK, since it
remains NULL when steerable UD QPs are not allocated).

The Gemini ethernet has been around for years as an out-of-tree
patch used with the NAS boxen and routers built on StorLink
SL3512 and SL3516, later Storm Semiconductor, later Cortina
Systems. These ASICs are still being deployed and brand new
off-the-shelf systems using it can easily be acquired.
The full name of the IP block is "Net Engine and Gigabit
Ethernet MAC" commonly just called "GMAC".
The hardware block contains a common TCP Offload Enginer (TOE)
that can be used by both MACs. The current driver does not use
it.

I see two issues with parameter new_link:
1. It's not needed. See also phy_interrupt(), works w/o this parameter.
phy_mac_interrupt sets the state to PHY_CHANGELINK and triggers the
state machine which then calls phy_read_status. And phy_read_status
updates the link state.
2. phy_mac_interrupt is used in interrupt context and getting the link
state may sleep (at least when having to access the PHY registers
via MDIO bus).
So let's remove it.

ppp_dev_uninit(), which is the .ndo_uninit() handler of PPP devices,
needs to lock pn->all_ppp_mutex. Therefore we mustn't call
register_netdevice() with pn->all_ppp_mutex already locked, or we'd
deadlock in case register_netdevice() fails and calls .ndo_uninit().
Fortunately, we can unlock pn->all_ppp_mutex before calling
register_netdevice(). This lock protects pn->units_idr, which isn't
used in the device registration process.
However, keeping pn->all_ppp_mutex locked during device registration
did ensure that no device in transient state would be published in
pn->units_idr. In practice, unlocking it before calling
register_netdevice() doesn't change this property: ppp_unit_register()
is called with 'ppp_mutex' locked and all searches done in
pn->units_idr hold this lock too.

__phy_modify would return the old value of the register before it was
modified. Thus on success, it does not return 0, but a positive value.
Thus functions using phy_modify, which is a wrapper around
__phy_modify, can start returning > 0 on success, rather than 0. As a
result, breakage has been noticed in various places, where 0 was
assumed.
Code inspection does not find any current location where the return of
the old value is currently used. So have __phy_modify return 0 on
success. When there is a real need for the old value, either a new
accessor can be added, or an additional parameter passed.

This patch adds a rhastable for mac address lookup of hwsim radios. This
especially improve the speed on reception of a netlink message with a new
frame. Although redundant, we keep holding a normal list for all radios,
since the rhashtable_walk interface adds a lot of overhead for iterating
over all radios and the doc of rhashtable recommend a redundant structure
for stable walks in such situations.
Since rhashtable is rcu protected we do not need a lock for delivering
frames and thus improving this scenario.

10GbE Intel Wired LAN Driver Updates 2018-01-12
This series contains updates to ixgbe, fm10k and net core.
Alex updates the driver to remove a duplicate MAC address check and
verifies that we have not run out of resources to configure a MAC rule
in our filter table. Also do not assume that dev->num_tc was populated
and configured with the driver, since it can be configured via mqprio
without any hardware coordination. Fixed the recording of stats for
MACVLAN in ixgbe and fm10k instead of recording the receive queue on
MACVLAN offloaded frames. When handling a MACVLAN offload, we should
be stopping/starting traffic on our own queues instead of the upper
devices transmit queues. Fixed possible race conditions with the
MACVLAN cleanup with the interface cleanup on shutdown. With the
recent fixes to ixgbe, we can cap the number of queues regardless of
accel_priv being in use or not, since the actual number of queues are
being reported via real_num_tx_queues.
Tony fixes up the kernel documentation for ixgbe and ixgbevf to resolve
warnings when W=1 is used.

Support basic stats for PRIO qdisc, which includes tx packets and bytes
count, drops count and backlog size. The rest of the stats are irrelevant
for this qdisc offload.
Since backlog is not only incremental but reflecting momentary value, in
case of a qdisc that stops being offloaded but is not destroyed, backlog
value needs to be updated about the un-offloading.
For that reason an unoffload function is being added to the ops struct.

Now that the kernel supports weighted IPv6 nexthops, we can extend the

This is done by assigning each nexthop its configured weight, so that it
will be populated accordingly in the device's adjacency table. The

The code throughout ixgbe was assuming that dev->num_tc was populated and
configured with the driver, when in fact this can be configured via mqprio
without any hardware coordination other than restricting us to the real
number of Tx queues we advertise.
Instead of handling things this way we need to keep a local copy of the
number of TCs in use so that we don't accidentally pull in the TC
configuration from mqprio when it is configured in software mode.

We might as well configure the limit to default to 1 pool always for the
interface. This accounts for the fact that the PF counts as 1 pool if
SR-IOV is enabled, and in general we are always running in 1 pool mode when
RSS or DCB is enabled as well, though we don't need to actually evaluate
any of the VMDq features in those cases.

The macvlan driver itself will validate the MAC address that is configured
for a given interface. There is no need for us to verify it again.
Instead we should be checking to verify that we actually allocate the filter
and have not run out of resources to configure a MAC rule in our filter
table.

Local variable "changed" was defined to indicates features changed,
but was used only for feature NETIF_F_HW_VLAN_CTAG_RX. Add checking
for other features.
