Subject: [PATCH net-next,v2 0/2] net: sched: introduce em_ipt ematch

From: Eyal Birger <eyal@...anetworks.com>

The following patchset introduces a new tc ematch for matching using
netfilter matches.

This allows early classification as well as mirroning/redirecting traffic
based on logic implemented in netfilter extensions.

Example use case is classification based on the incoming IPSec policy used
during decpsulation using the 'policy' iptables extension (xt_policy).

This patchset is an enhancement of a former series ([1]) which allowed only
policy matching following a suggestion by Pablo Neira Ayuso ([2]).
