[PATCHv2 0/7] OVS conntrack fixes for net

[Joe Stringer <joestringer@nicira.com>]

The userspace side of the Open vSwitch conntrack changes is currently
undergoing review, which has highlighted some minor bugs in the existing
conntrack implementation in the kernel, as well as pointing out some
future-proofing that can be done on the interface to reduce the need for
additional compatibility code in future.

The biggest changes here are to the userspace API for the ct_state match
field and the CT action. This series proposes to firstly extend the ct_state
match field to 32 bits, ensuring to reject any currently unsupported bits.
Secondly, rather than representing CT action flags within a 32-bit field,
simply use a netlink attribute as presence of the single flag that is
defined today. This also serves to reject unsupported ct action flag bits.
