Subject: [PATCH net 0/2] wireguard: device: fix metadata_dst xmit null pointer dereference

Hi,
Patch 01 fixes a null pointer dereference in wireguard's xmit path when
transmitting skbs with metadata_dst attached. Patch 02 adds a selftest for
that case using bpf_skb_set_tunnel_key on wg device's egress path.

Thanks,
 Nik
