OVS already has compat functions to handle GSO packets.
Following patch get rid of GSO packet handling in lisp
and use ovs iptunnel_xmit() function for same.

Generic tunnel rcv and send function are only used by lisp tunneling
module, so It make sense to move them to lisp module.

Following patch restructures ovs tunneling and gre vport
implementation to make ovs tunneling more in sync with
upstream kernel tunneling. Doing this tunneling code is
simplified as most of protocol processing on send and
recv is pushed to kernel tunneling. For external ovs
module the code is moved to kernel compatibility code.

VPORT_F_TUN_ID is last remaining flag, once we remove it, flags
field from vport-ops can be removed. Since it does not complicate
much code, we decided to remove this flag.

After flow based tunneling, kernel tunneling is greatly simplified.
There is no need to have extra tunneling layer between vport and
particular protocol.
Following patch removes tunneling struct which make code easy to read.

Since userspace flow based tunneling code is checked in, the kernel
port based tunneling code can be removed.
Patch removes following components:
- tunnel ports hash table and moved tunnel ports list to individual
vports.
- Cleaned per tnl-port config.
- OVS_KEY_ATTR_TUN_ID action is removed.

Bug #15078
LISP is an experimental layer 3 tunneling protocol, described in RFC
6830. This patch adds support for LISP tunneling. Since LISP
encapsulated packets do not carry an Ethernet header, it is removed
before encapsulation, and added with hardcoded source and destination
MAC addresses after decapsulation. The harcoded MAC chosen for this
purpose is the locally administered address 02:00:00:00:00:00. Flow
actions can be used to rewrite this MAC for correct reception. As such,
this patch is intended to be used for static network configurations, or
with a LISP capable controller.
