From: Bernhard Thaler Date: Sat, 30 May 2015 13:29:02 +0000 (+0200) Subject: netfilter: bridge: rename br_parse_ip_options X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=77d574e7283cfcbb2c134f4431f77dff1c54423e;p=openwrt%2Fstaging%2Fblogic.git 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.
