No ARP reply

Hi Alexander,

I only changed the IP since I do not think changing the mask using the
following commands is supported:

./usrp_burn_mb_eeprom --args="addr=xxx.xxx.xxx.xxx" --key=*subnet *
--val=255.255.255.0
./usrp_burn_mb_eeprom --args="addr=xxx.xxx.xxx.xxx"  --key=*gateway *
--val=xxx.xxx.xxx.xxx

I'm doing some more tracing soon.

Regards
Craig
