From: Ido Schimmel Date: Mon, 17 Jul 2017 12:15:30 +0000 (+0200) Subject: mlxsw: spectrum: Trap IPv4 packets with Router Alert option X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7607dd35fc34893214284cca740d015154d20452;p=openwrt%2Fstaging%2Fblogic.git mlxsw: spectrum: Trap IPv4 packets with Router Alert option In case local sockets have the IP_ROUTER_ALERT socket option set, then they expect to get packets with the Router Alert option. Trap such packets, so that the kernel could inspect them and potentially send them to interested sockets. Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S.
