netfilter: bridge: rename br_parse_ip_options
br_parse_ip_options() does not parse any IP options, it validates IP packets as a whole and the function name is misleading. Rename br_parse_ip_options() to br_validate_ipv4() and remove unneeded commments. Signed-off-by: Bernhard Thaler <bernhard.thaler@wvnet.at> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
