Subject: [PATCH net-next v2 0/2] udp_tunnel: convert mlx5 to the new udp_tunnel infrastructure

This set converts mlx5 to the new infrastructure.

We need a small amount of special handling as mlx5 expects IANA VXLAN
port to always be programmed into the device. ethtool will show such
ports in a separate, type-less, fake table, at the end:

Tunnel information for eth0:
  UDP port table 0: 
    Size: 7
    Types: vxlan
    No entries
  UDP port table 1: 
    Size: 1
    Types: none (static entries)
    Entries (1):
        port 4789, vxlan

Saeed - this should apply on top of net-next, independently of
the Intel patches, would you mind taking this in for testing
and review? I'll post the netdevsim & test once Intel patches
re-emerge.

v2: - don't disable the offload on reprs in patch #2.
