Subject: geneve: fix fill_info when using collect_metadata

From: Eric Garver <[email protected]>

[ Upstream commit 11387fe4a98f75d1f4cdb3efe3b42b19205c9df5 ]

Since 9b4437a5b870 ("geneve: Unify LWT and netdev handling.") fill_info does not return UDP_ZERO_CSUM6_RX when using COLLECT_METADATA. This is because it uses ip_tunnel_info_af() with the device level info, which is not valid for COLLECT_METADATA.

Fix by checking for the presence of the actual sockets.
