net: RTA_MARK addition
Add a new rt attribute, RTA_MARK, and use it in rt_fill_info()/inet_rtm_getroute() to support following commands : ip route get 192.168.20.110 mark NUMBER ip route get 192.168.20.108 from 192.168.20.110 iif eth1 mark NUMBER ip route list cache [192.168.20.110] mark NUMBER Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
