From 0c4231c784b4a0435a31f42451c66186c6e43170 Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Thu, 27 Jun 2019 11:10:47 +0300 Subject: [PATCH] net: sched: em_ipt: add support for addrtype matching Allow em_ipt to use addrtype for matching. Restrict the use only to revision 1 which has IPv6 support. Since it's a NFPROTO_UNSPEC xt match we use the user-specified nfproto for matching, in case it's unspecified both v4/v6 will be matched by the rule. v2: no changes, was patch 5 in v1 Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S.
