Dave,
These fixes are additive on top of the previous request archived here:
http://marc.info/?l=linux-wireless&m=119439453721827&w=2
I've been sending ssb patches to you, but I'm not sure if that is the
right place to send them. If you don't want them, can you suggest where
else I should send them?
Anyway, let me know if there are any problems!
Thanks,
John
