 That's a bit optimistic that attach and firmware loading is half of
the work no ?
 I don't know how much linuxkpi layer is needed for 80211 compat but I
guess it's "a lot" ?

 IIRC Linux have multiple 80211 framework no ?
 I guess your work only focus on one (used by iwlwifi), do you know how
many drivers used the same one ? What about FullMAC drivers like the
SDIO broadcom one used in many ARM SBC, is that using the same
framework ?
