====================
Mellanox, mlx5 fixes 2020-01-24

This series introduces some fixes to mlx5 driver.

Please pull and let me know if there is any problem.

Merge conflict: once merge with net-next, a contextual conflict will
appear in drivers/net/ethernet/mellanox/mlx5/core/eswitch_offloads.c
since the code moved in net-next.
To resolve, just delete ALL of the conflicting hunk from net.
So sorry for the small mess ..

For -stable v5.4:
 ('net/mlx5: Update the list of the PCI supported devices')
 ('net/mlx5: Fix lowest FDB pool size')
 ('net/mlx5e: kTLS, Fix corner-case checks in TX resync flow')
 ('net/mlx5e: kTLS, Do not send decrypted-marked SKBs via non-accel path')
 ('net/mlx5: Eswitch, Prevent ingress rate configuration of uplink rep')
 ('net/mlx5e: kTLS, Remove redundant posts in TX resync flow')
 ('net/mlx5: DR, Enable counter on non-fwd-dest objects')
 ('net/mlx5: DR, use non preemptible call to get the current cpu number')
====================
