So you want to counterfeit the MAC ?

Sound like you run a very reputable store

A customer modified the MAC address of one port on my Network Interface Card (NIC) to FFFFFFFFFFFF, which has caused the port to become inoperative. I would like to repair it.

Besides this weird feeling why somebody would mess with the mac addresses, I would expect the broadcom documentation to have information how to recover cards and set all guids, base mac adresses etc...

There's plenty of valid reasons to change the mac address of an interface; nothing "bad" or "shady" about it...
E.g. some ISPs require you to use DHCP for fixed IPs and will only attach that lease to the mac of their provided plastic router, even for business lines.

Usually you can simply set the mac address via ifconfig:
ifconfig bge0 ether random|<mac> or ifconfig bge0 lladdr random|<mac>
just use the default configuration for interfaces (e.g. rc.conf or hostname.if) to make this permanent/get set at boot.

To set the mac at the firmware level you might get some hints from the manpage of the driver; but given this is broadcom I suspect you'd need some proprietary, crappy windows tool...
TBH I wouldn't bother about the address in the eeprom if there's no tool readily available - just set the mac via the interface configuration and call it a day.

I tried recovering the controller card with niccli, but it didn't make much of a difference

Appreciate it. I'll test the tool on Linux.

hello, it will not change the mac permanently

Masquerading MAC using software is a very different thing altogether, than wanting to change the physical MAC on NIC

One is normal practice in many scenarios, the other is NOT
