Subject: openvswitch: Remove redundant tcp_flags code.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1b760fb9a8a8c0babc15f886ee5740cb33744168;p=openwrt%2Fstaging%2Fblogic.git

openvswitch: Remove redundant tcp_flags code.

These two cases used to be treated differently for IPv4/IPv6,
but they are now identical.
