It was the longest name in the whole list, so fair enough.

Took TNL_OPT_MISMATCH in v2: what gets compared is the options the
packet carries against the ones the tunnel is configured for, not the
configuration as a whole.

I also renamed the two other reasons this series adds for the generic
paths, IP_TUNNEL_OLD_SEQ and IP_TUNNEL_ENCAP, to TNL_OLD_SEQ and
TNL_ENCAP, so that the three do not end up split over two prefixes.
The GRE specific ones keep the GRE_ prefix, next to the VXLAN_ ones.
