Yes, but that is not significant, because the Ethernet headers are constructed in software, so you could in theory tell the link layer driver to use a different MAC address; but then you'd have to run in promiscuous mode constantly and sort packets in software, because there's (generally) no way to tell the NIC to use a different address, so it'd discard packets bearing your (fake) MAC address as destination address. -- Noone else has a .sig like this one.
