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 <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
