[PATCH 0/3] staging: wlags49_h2: Improve WEXT support

[David Kilroy]

There are reports of issues using WPA with this driver. This series of
patches fixes a few obvious issues with the WEXT support in this
driver.

The changes have not recieved any testing. YMMV.

[PATCH 1/3] staging: wlags49_h2: Remove old WIRELESS_EXT support

[David Kilroy]

Since the driver is now in-kernel remove support for building
against ancient WIRELESS_EXT versions.

[PATCH 2/3] staging: wlags49_h2: Support standard WEXT events

[David Kilroy]

... instead of using IWEVCUSTOM. Use the defined events for
michael mic failure, association request info and association
response info.

[PATCH 3/3] staging: wlags49_h2: Declare support for WEXT 21

[David Kilroy]

There may be a few areas where we don't actually support WE21,
but by doing this it will make it easier to find those places.

I'll bite - what happens when we find such a place?  Kernel fails to build, or
user has a suboptimal usage experience, or?

What are the expected chances that sticking this in linux-next for a cycle will
result in most/all of the places being found before this all appears in an
official release?  I'm thinking this should probably go in linux-next right after
the next merge window closes, to maximize the chances we'll shake it
all out during almost 2 cycles before it hits the streets. (And yes, I know
it's a staging/ driver - if somebody else says "one cycle is more than enough"
I'm OK with that too...)

The user would have a sub-optimal experience. iwconfig may not display a 
few things correctly (ESSID?) in particular scenarios.

The reason I included this patch was that I'm not sure whether 
wpa-supplicant requires WEXT version to be above a certain threshold to 
use the events in the previous patch. I'm happy to drop this one if it 
just works.

This hardware is old, and as far as I can tell quite rare. I'd hope we 
can get some feedback from Henk on the series before applying this patch.

Thanks,

Dave.

I've applied the first 2 of these, if you want me to apply the third
one, please resend it after it's been tested by someone.

I have the patched driver running on the 2.6.38-11-generic #48 Ubuntu 
11.04 Natty Narwhal kernel, which, as far as I could determine, uses WEXT 
version 22. The patch didn't improve anything other than the code itself, 
but didn't break anything either. Tested with WEP accesspoint, WPA still 
not functional. The still appears to be stable.

Henk.

So, should I apply this patch or not?

It doesn't break anything and is was there to make sure the previous 
patches work, so yes, why not.

Ok, can someone please resend it then, it's long-gone from my patch
queue at this point in time.

Thanks Greg. I'll take the time to find out what's actually changed in 
the WEXT versions, and resend towards the end of this week with any 
necessary fixes.

Dave.
