The android phone I looked at briefly was running an Atheros
based NIC, but it did not support more than one station VIF.

Possibly other systems can do more, but I think it is not
very likely.

In general, if you want multiple stations vifs, you need
ath9k, and for more than just a few stations, you need a
pci or pci-e based NIC (not USB).

Ath5k might work in some cases, and with proper firmware and
some driver tweaks, ath10k should support some as well.

Thanks,
Ben
