Subject: [PATCH net-next v2 0/4] em_ipt: add support for addrtype

Hi,
We would like to be able to use the addrtype from tc for ACL rules and
em_ipt seems the best place to add support for the already existing xt
match. The biggest issue is that addrtype revision 1 (with ipv6 support)
is NFPROTO_UNSPEC and currently em_ipt can't differentiate between v4/v6
if such xt match is used because it passes the match's family instead of
the user-specified one. The first 3 patches make em_ipt match only on IP
traffic (currently both policy and addrtype recognize such traffic
only) and make it pass the actual packet's protocol instead of the xt
match family when it's unspecified. They also add support for NFPROTO_UNSPEC
xt matches. The last patch allows to add addrtype rules via em_ipt.

v2: change patch 02 to set the nfproto only when unspecified and drop
    patch 04 from v1 (Eyal Birger)

Thank you,
  Nikolay Aleksandrov

  net: sched: em_ipt: match only on ip/ipv6 traffic
  net: sched: em_ipt: set the family based on the packet if it's
    unspecified
  net: sched: em_ipt: keep the user-specified nfproto and use it
  net: sched: em_ipt: add support for addrtype matching
