* ``mac``: Changes the source and the destination Ethernet addresses of
packets before forwarding them.
+ Default application behaviour is to set source Ethernet address to that of
the transmitting interface, and destination
+ address to a dummy value (set during init). The user may specify a target
destination Ethernet address via the 'eth-peer' or
+ 'eth-peer-configfile' command-line options. It is not currently possible to
specify a specific source Ethernet address.
* ``macswap``: MAC swap forwarding mode.
Swaps the source and the destination Ethernet addresses of packets before
forwarding them.
