The MAC layer is almost invariably implemented in hardware for modern
network interfaces.  In the case of wireless networks, that's usually
firmware running on a microcontroller inside the card, although
controllers differ as to the amount of functionality assumed by the
firmware.

FreeBSD's network stack implements support for Ethernet-like devices
from the LLC sublayer up.
