William Tu 9a1381d509 gre: add support for ERSPAN tunnel
The patch adds ERSPAN type II tunnel support. The implementation is
based on the draft at
 https://tools.ietf.org/html/draft-foschiano-erspan-01.

One of the purposes is for Linux box to be able to receive ERSPAN
monitoring traffic sent from the Cisco switch, by creating a ERSPAN
tunnel device. In addition, the patch also adds ERSPAN TX, so traffic
can also be encapsulated into ERSPAN and sent out.

The implementation reuses the key as ERSPAN session ID, and
field 'erspan' as ERSPAN Index fields:
./ip link add dev ers11 type erspan seq key 100 erspan 123 \
		local 172.16.1.200 remote 172.16.1.100

How to compile this.
--------------------
1. libdbm

arpd needs to have the db4 development libraries. For Debian
users this is the package with a name like libdb4.x-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines.  Often this is in the db-devel package.

2. make

The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.

3. To make documentation, cd to doc/ directory , then
   look at start of Makefile and set correct values for
   PAGESIZE=a4		, ie: a4 , letter ...	(string)
   PAGESPERPAGE=2	, ie: 1 , 2 ...		(numeric)
   and make there. It assumes, that latex, dvips and psnup
   are in your path.

4. This package includes matching sanitized kernel headers because
   the build environment may not have up to date versions. See Makefile
   if you have special requirements and need to point at different
   kernel include files.
