====================
mlx5 IPsec packet offload support in eswitch mode

This series from Jianbo adds mlx5 IPsec packet offload support in eswitch
offloaded mode.

It works exactly like "regular" IPsec, nothing special, except
now users can switch to switchdev before adding IPsec rules.

 devlink dev eswitch set pci/0000:06:00.0 mode switchdev

Same configurations as here:

https://lore.kernel.org/netdev/cover.1670005543.git.leonro@nvidia.com/

Packet offload mode:
  ip xfrm state offload packet dev <if-name> dir <in|out>
  ip xfrm policy .... offload packet dev <if-name>
Crypto offload mode:
  ip xfrm state offload crypto dev <if-name> dir <in|out>
or (backward compatibility)
  ip xfrm state offload dev <if-name> dir <in|out>
