I think you'd end up mapping the MAC of the PC to the STA, 1-to-1 mapping,
and possibly re-writing the src MAC when coming from the PC to the STA,
and dest MAC when coming from STA to PC.

Users wanting more than one PC could use a different virtual STA.

Did it at least work for 1-to-1 mapping OK?  Did you re-write MACs?

Thanks,
Ben
