Subject: [PATCH 0/2] Interface groups, round two

Hello,

Here is the new version of ifgroup patches.

The interface group value is u_int32_t in net_device which should be enough.
Previously it was an int.

Usage:
   ip link set eth0 group 4
but currently it cannot be unset, only changed to another value.

In /etc/iproute2/rt_ifgroup each value may have a symbolic name.

Netfilter part: xt_ifgroup module for both IPv4 and IPv6. Iptables usage:
   iptables -A INPUT -m ifgroup --in-ifgroup 4/0xf -j ACCEPT
   iptables -A FORWARD -m ifgroup --in-ifgroup 4 --out-ifgroup 5 -j ACCEPT
   ...

in the FORWARD chain both input and output interface group value should be matched
(with optional masks).

The following patches are:
  kernel: core part
  kernel: netfilter module, ifgroup match
  iproute2: showing and set ifgroup value
  iptables: ifgroup match
