Right, because mwl8k supports only the softmac 8687 PCI-E parts right
now.  It doesn't yet support the 8335 or 8310 or 86xx TopDog parts yet.
There hasn't been any movement on those for a while and I haven't gotten
around to abstracting mwl8k's hardware support to handle the older
parts.  But mwl8k is the only driver that could possibly be relevant for
you, since libertas will always be for the fullmac-only parts (8385,
8388, 8686, 8688).
