Merge branch 'net_next_ovs' of git://git.kernel.org/pub/scm/linux/kernel/git/pshelar/openvswitch

Pravin B Shelar says:

====================
Open vSwitch

Following patches adds recirculation and hash action to OVS.
First patch removes pointer to stack object. Next three patches
does code restructuring which is required for last patch.
Recirculation implementation is changed, according to comments from
David Miller, to avoid using recursive calls in OVS. It is using
queue to record recirc action and deferred recirc is executed at
the end of current actions execution.

v1-v2:
Changed subsystem name in subject to openvswitch
v2-v3:
Added patch to remove pkt_key pointer from skb->cb.
