Saeed Mahameed says:

====================
mlx5-updates-2020-03-29

1) mlx5 core level updates for mkey APIs + migrate some code to mlx5_ib

2) Use a separate work queue for fib event handling

3) Move new eswitch chains files to a new directory, to prepare for
upcoming E-Switch and offloads features.

4) Support indr block setup (TC_SETUP_FT) in Flow Table mode.
====================
