Subject: net/mlx5e: Sync VXLAN udp ports during uplink representor profile

 change

Patch-mainline: v5.17-rc1

Git-commit: 07f6dc4024ea1d2314b9c8b81fd4e492864fcca1

References: git-fixes

Currently during NIC profile disablement all VXLAN udp ports offloaded to the

HW are flushed and during its enablement the driver send notification to

the stack to inform the core that the entire UDP tunnel port state has been

lost, uplink representor doesn't have the same behavior which can cause

VXLAN udp ports offload to be in bad state while moving between modes while

VXLAN interface exist.

Fixed by aligning the uplink representor profile behavior to the NIC behavior.

Fixes: 84db66124714 ("net/mlx5e: Move set vxlan nic info to profile init")
