This change adds optional IPv4 DNAT support to l2fwd module for level two
forwarding. With this change the l2fwd module can be used for testing
complex IP configuration routing with virtual switches.
Other L2 forwarding modules provide only Level 2 pass through. These can be
used for complex IP chain processing but rely on port forwarding in the switch.
With this module each packet which is forwarded optionally gets a new
destination IP and source masquerade. So a test packet can be routed to eth1
and forwarded on eth2 with a different target IP and source address.
To use this module compile it for your kernel and use the 'insmod' command
to insert it.
With no arguments this will forward eth1 to eth2 without modification.
With 'net1=ethX net2=ethX' Level 2 forwarding can be done between arbitrary
ports.
With 'netX=ethX,XX.XX.XX.XX,xx:xx:xx:xx:xx:xx' the packets which are forwarded
on the target port will be given the new destination IP and mac address. One
or both ports may enable DNAT.

This commit adds a simple kernel module for l2 forwarding or termination
This module provides only level 2 forwarding between two ports, it does not
do any NAT or Masquerade.
Arguments are:
net1=ethXXXX # set forwarding port 1
net2=ethXXX # set forwarding port 2
terminate=1 # terminate the connection and free the skb
Changed to GPL licensing to avoid compilation issues
Added sanity build target
Fix whitespace issues
