vxlan: Add missing entries to vxlan_get_size()

There are some attributes added by vxlan_fill_info() which are not accounted for in vxlan_get_size(). Add them. I didn't find a way to trigger an actual problem from this miscalculation since there is usually extra space in netlink size calculations like if_nlmsg_size(); but maybe I just didn't search long enough. Fixes: 3511494 ("vxlan: Group Policy extension") Fixes: e1e5314 ("vxlan: implement GPE") Fixes: 0ace2ca ("vxlan: Use checksum partial with remote checksum offload") Fixes: f9c4bb0 ("vxlan: vni filtering support on collect metadata device") Signed-off-by: Benjamin Poirier <[email protected]> Acked-by: Nikolay Aleksandrov <[email protected]> Reviewed-by: Ido Schimmel <[email protected]> Signed-off-by: David S.
