Change the order to first route IPv4/6 and return if error. Only after
successful route continue to allocate an encap header, with no
functional change.

In tunnel encap we prepare the encap header for IPv4/6 cases, in two
separate functions. For ETH header generation the code is almost
duplicated.
Move the ETH header generation code from IPv4/6 functions to a helper
function, with no functional change.

Currently we don't support nor fail attempts to offload encap flows routed
to vlan device on the underlay network. We wrongly consider a vlan underlay
device to be on the same e-switch b/c the switchdev ID is retrieved recursively.
Add explicit check for that and fail such attempts.
Also align to a more strict check for the ingress and the underlay devices
to practically be on the same eswitch.

We use the switchdev parent HW id helper to identify if the mirred device
shares the same ASIC/port with the ingress device. This can get us wrong
in the presence of upper devices such as vlan or bridge set over the HW
devices (VF or uplink representors), b/c the switchdev ID is retrieved
recursively.
To fail offload attempts in such cases, we condition the check on the
egress device to have not only the same switchdev ID but also the relevant
mlx5 netdev ops.

There are cases (e.g tunneling with vlan on underlay and potentially

The default size for the VF representors' SQ was too small to handle high
packet rates. Doubling the size from 64 to 128 drastically improves the
packet rate under stress (by about 50%), whereas increasing the size
beyond 128 has not shown to make any further difference.
The impact of the SQ size was measured with UDP traffic, in the following
topology: TG <-> PF <-> TC forwarding <-> VF representor <-> VF in VM
over a single core processing bi-directional traffic, with the following
results:
SQ size of 64: SQ size of 128:
Packet rate for 64B UDP packets: 860 [Kpps] 1280 [Kpps]
Packet rate for 114B VxLan
encapsulated UDP packets: 320 [Kpps] 500 [Kpps]

The timecounter needs to be updated at least once in half of the
cyclecounter interval to prevent timecounter_cyc2time() interpreting a
new timestamp as an old value and causing a backward jump.
This would be an issue if the timecounter multiplier was so small that
the update interval would not be limited by the 64-bit overflow in
multiplication.
Shorten the calculated interval to make sure the timecounter is updated
in time even when the system clock is slowed down by up to 10%, the
multiplier is increased by up to 10%, and the scheduled overflow check
is late by 15%.

The MAC Reset was noticed to erase important EEPROM settings.
It is also unnecessary since a chip wide reset was done earlier
in initialization, and that reset preserves EEPROM settings.
There for this patch removes the unnecessary MAC specific reset.

this patch registers neigh doit handler. The doit handler
returns a neigh entry given dst and dev. This is similar
to route and fdb doit (get) handlers. Also moves nda_policy
declaration from rtnetlink.c to neighbour.c

When the completion queue of the RQ is empty, do not immediately return.
If left-over decompressed CQEs (from the previous cycle) were processed,
need to go to the finalization part of the poll function.
Bug exists only when CQE compression is turned ON.
This solves the following issue:

====================
mlxsw: Make driver more robust
In recent months we fixed several bugs in the driver that could have
been avoided by re-evaluating some of the involved code paths and by
introducing relevant and comprehensive test cases.
This patchset tries to do that by introducing a set of small and mostly
non-functional changes in addition to a new test. I have further
improvements in mind, but they can be done in a different set.
Patch #1 makes sure we correctly sanitize upper devices of a VLAN
interface.
Patch #2 removes an unexpected behavior from the driver, in which routes
configured on a VLAN interface will cease being offloaded after certain
operations.
Patch #3 is a small cleanup.
Patch #4 simplifies the driver by removing reference counting from VLAN
entries configured on a port.
Patches #5-#6 simplify linking/unlinking from a bridge, especially when
LAG and VLAN devices are involved. They make both operations symmetric
even when ports are unlinked from a bridged LAG device.
Patch #7-#9 make router interface (RIF) deletion more robust by removing
reliance on device chain to indicate whether a NETDEV_DOWN event in the
inet{,6}addr notification chains should be processed. This is due to the
fact that IP addresses can be flushed from a netdev after it was
unlinked from its lower device.
Patch #10 adds a new test to for valid and invalid configurations over
mlxsw ports. Some of the test cases are derived from recent fixes. I
expect that more test cases will be added over time.

Add a new test that is focused on rtnetlink configuration. Its purpose
is to test valid and invalid (as deemed by mlxsw) configurations and
make sure that they succeed / fail without producing a trace.
Some of the test cases are derived from recent fixes in order to make
sure that the fixed bugs are not introduced again.

Previous patches tried to make RIF deletion more robust and avoid
use-after-free situations.
As another precaution, hold a reference on a RIF's netdev and release it
when the RIF is deleted.
