Merge branch 'mlx5-SRIOV-offload-tunnel_key-set-release' 

Saeed Mahameed says:

====================
Mellanox 100G SRIOV offloads tunnel_key set/release

From Hadar Hen Zion:

This series further enhances the SRIOV TC offloads of mlx5 to handle the
TC tunnel_key release and set actions.

This serves a common use-case in virtualization systems where the virtual
switch encapsulate packets (tunnel_key set action) sent from VMs with
outer headers corresponding to the local/remote host IPs and de-capsulate
(tunnel_key release) outer headers before the packets are received by the
VM.

We use the new E-Switch switchdev mode and TC tunnel_key set/release
action to achieve that also in SW defined SRIOV environments by
offloading TC rules that contain these actions along with forwarding
(TC mirred/redirect action) the packets.

The first six patches are adding the needed support in flow dissector,
flower and tc for offloading tunnel_key actions:
    - The first three patches are adding the needed help functions
      and enums
    - The next three patches in the series are adding UDP port attribute
      to tunnel_key release and set actions.

The addition of UDP ports would allow the HW driver to make sure they are
given (say) a VXLAN tunnel to offload (mlx5e uses that).

Patches 7-10 are mlx5 preparations for tunnel_key actions offloads support.

Patch #11 adds mlx5e support to offload tunnel_key release action, and the
last two patches (#12-13) add mlx5e support to tc tunnel_key set action.

Currently in order to offload tc tunnel_key release action, the tc rule
should be placed on top of the mlx5e offloading (uplink) interface instead
of the shared tunnel interface. The resolution between the tunnel interface
to the HW netdevice will be implemented in a follow up series.

This series was generated against commit
94edc86b ("Merge branch 'dwmac-sti-refactor-cleanup'")
