From 2000eeb975c70f03c6495511d6f81868dd871165 Mon Sep 17 00:00:00 2001 From: Maor Dickman Date: Mon, 3 Jan 2022 15:04:18 +0200 Subject: [PATCH] net/mlx5e: Sync VXLAN udp ports during uplink representor profile change 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.
