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.
