The following PR includes updates to mlx5-next branch:
Headlines:
==========
1) Jakub cleans up unused static inline functions
2) I did some low level firmware command interface return status changes to
provide the caller with full visibility on the error/status returned by
the Firmware.
3) Use the new command interface in RDMA DEVX usecases to avoid flooding
dmesg with some "expected" user error prone use cases.
4) Moshe also uses the new command interface to grab the specific error
code from MFRL register command to provide the exact error reason for
why SW reset couldn't perform internally in FW.
5) From Mark Bloch: Lag, drop packets in hardware when possible
In active-backup mode the inactive interface's packets are dropped by the
bond device. In switchdev where TC rules are offloaded to the FDB
this can lead to packets being hit in the FDB where without offload
they would have been dropped before reaching TC rules in the kernel.
Create a drop rule to make sure packets on inactive ports are dropped
before reaching the FDB.
Listen on NETDEV_CHANGEUPPER / NETDEV_CHANGEINFODATA events and record
the inactive state and offload accordingly.

mlx5_core_create_{cq/dct} functions are non-trivial mlx5 commands
functions. They check command execution status themselves and hide
valuable FW failure information.
For mlx5_core/eth kernel user this is what we actually want, but for a
devx/rdma user the hidden information is essential and should be propagated
up to the caller, thus we convert these commands to use mlx5_cmd_do
to return the FW/driver and command outbox status as is, and let the caller
decide what to do with it.
For kernel callers of mlx5_core_create_{cq/dct} or those who only care about
the binary status (FAIL/SUCCESS) they must check status themselves via
mlx5_cmd_check() to restore the current behavior.
err = mlx5_create_cq(in, out)
err = mlx5_cmd_check(err, in, out)
if (err)
// handle err
For DEVX users and those who care about full visibility, They will just
propagate the error to user space, and app can check if err == -EREMOTEIO,
then outbox.{status,syndrome} are valid.
API Note:
mlx5_cmd_check() must be used by kernel users since it allows the driver
to intercept the command execution status and return a driver simulated
status in case of driver induced error handling or reset/recovery flows.

The flow counters bulk query buffer is allocated once during
mlx5_fc_init_stats(). For PFs and VFs this buffer usually takes a little
more than 512KB of memory, which is aligned to the next power of 2, to
1MB. For SFs, this buffer is reduced and takes around 128 Bytes.
The buffer size determines the maximum number of flow counters that
can be queried at a time. Thus, having a bigger buffer can improve
performance for users that need to query many flow counters.
There are cases that don't use many flow counters and don't need a big
buffer (e.g. SFs, VFs). Since this size is critical with large scale,
in these cases the buffer size should be reduced.
In order to reduce memory consumption while maintaining query
performance, change the query buffer's allocation scheme to the
following:
- First allocate the buffer with small initial size.
- If the number of counters surpasses the initial size, resize the
buffer to the maximum size.
The buffer only grows and isn't shrank, because users with many flow
counters don't care about the buffer size and we don't want to add
resize overhead if the current number of counters drops.
This solution is preferable to the current one, which is less accurate
and only addresses SFs.
