I am not sure as:
1. I haven't yet gone through hostap code besides wpa_supplicant
2. I haven't yet gone through the available softmac code:
Only once I have done both will I be able to tell. My guess yes
as I do not think hostap is softmac based.

That's where I was going with my previous e-mail.

We need as much public information available on softmac and review, or
have someone experienced enough in this field to talk up.

Well at least this confirms another card will be softmac based, and
hence the possible need for code sharing.
