====================
mlx5-next 2022-22-02

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-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux:
  net/mlx5: Add clarification on sync reset failure
  net/mlx5: Add reset_state field to MFRL register
  RDMA/mlx5: Use new command interface API
  net/mlx5: cmdif, Refactor error handling and reporting of async commands
  net/mlx5: Use mlx5_cmd_do() in core create_{cq,dct}
  net/mlx5: cmdif, Add new api for command execution
  net/mlx5: cmdif, cmd_check refactoring
  net/mlx5: cmdif, Return value improvements
  net/mlx5: Lag, offload active-backup drops to hardware
  net/mlx5: Lag, record inactive state of bond device
  net/mlx5: Lag, don't use magic numbers for ports
  net/mlx5: Lag, use local variable already defined to access E-Switch
  net/mlx5: E-switch, add drop rule support to ingress ACL
  net/mlx5: E-switch, remove special uplink ingress ACL handling
  net/mlx5: E-Switch, reserve and use same uplink metadata across ports
  net/mlx5: Add ability to insert to specific flow group
  mlx5: remove unused static inlines
