Rename 'struct nf_conntrack_protocol' to 'struct nf_conntrack_l4proto' in order to help distinguish it from 'struct nf_conntrack_l3proto'. It gets rather confusing with 'nf_conntrack_protocol'. Signed-off-by: Martin Josefsson <gandalf@wlug.westbo.se> Signed-off-by: Patrick McHardy <kaber@trash.net>
