Seems we conflicted here, I've done the same for net.git to fix ICMP
path. I made parse_gre_header return the length instead of adding the
parameter, as it's easier consumed that way (no need for an extra local
variable in gre_err).

How do we resolve the conflict between net and net-next? I'd prefer
gre_parse_header to return the header length. I can submit a patch for
net-next that does this; that would substantially ease the merge.
