net/mlx5e: Fix VXLAN configuration restore after function reload (b3c2ed21) · Commits · 戴 / test

When detaching netdev, remove vxlan port configuration using udp_tunnel_drop_rx_info. During function reload, configuration will be restored using udp_tunnel_get_rx_info. This ensures sync between firmware and driver. Use udp_tunnel_get_rx_info even if its physical interface is down. Fixes: ("net/mlx5: Add devlink reload") Signed-off-by:
