I don't know.  I got this information because I lurk around the kernel ML
related to 802.11 stuff.

BTW, I think I was imprecise.  Apparently, the card can do AP mode on the
2.4GHz band, but I don't know which limitations it has.  It cannot do it at
all in the 5GHz band.

Yeah, my bad.  Apparently, AP mode is impossible only in the 5GHz band.

IME, if you want more functionality, you should go with Atheros.
