NOOOoooooo.
This is why I stated most people are wrong with their desire to change the
MAC address in the EEPROM. The H-A failover should be done only by
replacing the software copy of the MAC address, not by crudely hacking the
EEPROM, which won't change the current value anyway.
Some yahoo will change his two MAC addresses to be identical and then the
unfortunate sysadmin eventually ends up with a broken network.
