Subject: net/mlx5e: Sync netdev vxlan ports at open
From: Shahar Klein <shahark@mellanox.com>
[ Upstream commit a117f73dc2430443f23e18367fa545981129c1a6 ]
When mlx5_core is loaded it is expected to sync ports
with all vxlan devices so it can support vxlan encap/decap.
This is done via udp_tunnel_get_rx_info(). Currently this
call is set in mlx5e_nic_enable() and if the netdev is not in
NETREG_REGISTERED state it will not be called.
Normally on load the netdev state is not NETREG_REGISTERED
so udp_tunnel_get_rx_info() will not be called.
Moving udp_tunnel_get_rx_info() to mlx5e_open() so
it will be called on netdev UP event and allow encap/decap.
Fixes: 610e89e05c3f ("net/mlx5e: Don't sync netdev state when not registered")
