The libertas firmware doesn't do roaming *)

But it also doesn't allow for individual auth/deauth
assoc/disassoc things, e.g. with the libertas firmware you cannot
stay authenticated when and just disassociate/reassociate when
some settings changes.  Therefore I have an impedance mismatch 
between libertas and .auth/.deauth .assoc/.disassoc as well. The 
most in-the-eye-springing point is that libertas doesn't have a 
CMD_802_11_DEASSOCIATE command. And the 
CMD_802_11_DEAUTHENTICATE command does both .deauth/.disassoc 
one go. Another mismatch is that CMD_802_11_ASSOCIATE also does 
both .auth/.assoc in one go.

So, libertas is not really FULLMAC and not really SOFTMAC, it's 
HALFMAC :-)





*) however, it can send a disconnect event when the AP is out of
reach, this will give you poor-mans roaming with the help of 
wpa_supplicant.
