mac80211: Roaming issues.

mac80211: Roaming issues.

[Lars Ericsson]

Hi,

I have been working with Ivo for a while, testing/debugging the rt2x00
driver.

Parallel with that I have been testing the roaming performance in different
environments/sites.
I have discovered a number of improvement to the mac80211 driver that will
significantly speed up the roaming function. The actual roaming is of course
controlled form the wpa_supplicant, but with my patches, the
mac80211/wpa_supplicant will cooperate much smother and faster.

My question are:
- Is this the place to discuss the mac80211 driver ?
- How is 'responsible' for the mac80211 driver ?

Regards
Lars

Nit: mac80211 isn't a driver, it's the generic stack that is
used/cooperates with many drivers for many different types of hardware.

That's actually true only if you use wpa_supplicant which with open
networks you're not forced to.

Sounds good.

Yes.

I pretty much am, but also see the MAINTAINERS file (still lists Michael
Wu and Jiri Benc who both don't do anything any more). Please copy me on
all patches, but of course send them to the list.

Ok,

I put some suggestions and patches together and come back to the list.
