Hi,

I saw a couple of emails whizz by, which discussed how to override the
burned in MAC address (BIA) on an RPI-B.

First off I'm not familiar with the use or configuration of either a Pi or
FreeBSD, but to me it looked like in the emails a dependency between two
techniques, i.e. overriding the BIA of a NIC and configuring a NIC into
promiscuous mode, was made while such a dependency does not or at least, to
the best of my knowledge, should not exist.

I used, what in IBM lingo is referred to as a locally administered MAC
addresses, numerous times predominantly in the nineties of the previous
century in datacenter environments using equipment from big blue or its plug
compatible competitors, while such equipment exclusively used IBM's Systems
Network Architecture (SNA), i.e. non TCP/IP, protocols.

To the best of my recollection at the time there was no need whatsoever to
configure these NICs into promiscuous mode, which in itself is needed to
have a NIC consider frames that aren't destined for the NIC's BIA address as
if they were, so I doubt that such a need exists today.

I hope this helps, regards, Jk.
