aa310701e7 openvswitch: Add gre tunnel support.
Add gre vport implementation.  Most of gre protocol processing
is pushed to gre module. It make use of gre demultiplexer
therefore it can co-exist with linux device based gre tunnels.

74f84a5726 openvswitch: Copy individual actions.
Rather than validating actions and then copying all actiaons
in one block, following patch does same operation in single pass.
This validate and copy action one by one. This is required for
ovs tunneling patch.

This patch does not change any functionality.

f44f340883 openvswitch: Immediately exit on error in ovs_vport_cmd_set().
It is an error to try to change the type of a vport using the set
command. However, while we check that this is an error, we still
proceed to allocate memory which then gets freed immediately.
This stops processing after noticing the error, which does not
actually fix a bug but is more correct.

3a4e0d6a95 openvswitch: Use parallel_ops genl.
OVS locking was recently changed to have private OVS lock which
simplified overall locking.  Therefore there is no need to have
another global genl lock to protect OVS data structures.  Following
patch uses of parallel_ops genl family for OVS.  This also allows
more granual OVS locking using ovs_mutex for protecting OVS data
structures, which gives more concurrencey.  E.g multiple genl
operations OVS_PACKET_CMD_EXECUTE can run in parallel, etc.

The e{uid,gid} --> {uid,gid} credentials fix conflicted with the
cleanup in net-next to now pass cred structs around.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN
interface changes by Patrick McHardy in net-next.

An IGB conflict existed because in 'net' the build_skb() support was
reverted, and in 'net-next' there was a comment style fix within that
code.

Several batman-adv conflicts were resolved by making sure that all
calls to batadv_is_my_mac() are changed to have a new bat_priv first
argument.

Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO
rewrite in 'net-next', mostly overlapping changes.

Thanks to Stephen Rothwell and Antonio Quartulli for help with several
of these merge resolutions.

86a9bad3ab net: vlan: add protocol argument to packet tagging functions
Add a protocol argument to the VLAN packet tagging functions. In case of HW
tagging, we need that protocol available in the ndo_start_xmit functions,
so it is stored in a new field in the skb. The new field fits into a hole
(on 64 bit) and doesn't increase the sks's size.

8e4e1713e4 openvswitch: Simplify datapath locking.
Currently OVS uses combination of genl and rtnl lock to protect
datapath state.  This was done due to networking stack locking.
But this has complicated locking and there are few lock ordering
issues with new tunneling protocols.
Following patch simplifies locking by introducing new ovs mutex
and now this lock is used to protect entire ovs state.
