If you want roaming to keep oper state UP in all cases, then
yes. Does this work on full mac cards as well?
I don't see why not.
E.g. if I CMD_CONNECT to AP1, then pre-authenticate to AP2 and issue
a CMD_CONNECT to AP2?
That's not something you can do with full-MAC cards?
Err, why not? Pre-Authentication runs over a 0x88c7 protocol. So we
should get these just like regular PAE frames. But forget
pre-authentication, one can still force a roam between BSSes within the
same ESS by specifying NL80211_ATTR_PREV_BSSID. At least that's what
the docs say ;)
And even mac80211 doesn't really support pre-authentication (unless you
mean over-the-DS)
There's only one kind of preauthentication? Are you confusing this with
FT? We use FT-over-Air just fine on mac80211 and on real hardware. We
even have an autotest for this based on mac80211_hwsim. FT-over-DS
should work as well.
Full macs don't support FT due to lack of
CMD_ASSOCIATE/CMD_AUTHENTICATE. Can we fix that btw?
