I assume you want a hub to simulate multiple MACs behind the same port.
You don't need a hub for that. You can set the MAC using mausezahn. See
'-a' option:

"
   -a <src-mac|keyword>
       Use specified source MAC address with hexadecimal notation such
as 00:00:aa:bb:cc:dd.  By default the interface MAC address will be
used. The  keywords  ''rand''
       and  ''own''  refer to a random MAC address (only unicast
addresses are created) and the own address, respectively. You can also
use the keywords mentioned below
       although broadcast-type source addresses are officially invalid.

Ido, I am not so known to the selftests, so I am wondering why I don't 
see either check_err or check_fail fail, whichever I use, when I think 
they should and then they are not really checking...


         local mac=10:20:30:30:20:10


         $MZ $h1 -t udp -a $mac -b rand
         bridge fdb show dev $swp1 | grep -q "$mac vlan 1 master br0 
locked"
         check_err $? "MAB station move: no locked entry on first 
injection"

         $MZ $h2 -t udp -a $mac -b rand
         bridge fdb show dev $swp1 | grep -q "$mac vlan 1 master br0 
locked"
         check_err $? "MAB station move: locked entry did not move"

What is wrong here?

For a mv88e6xxx test I guess I can make a check to verify that this 
driver is in use?
