[Bug 55809] Re: HAL changes wireless interface (net.80211) to wired (net.80203) in info.category after suspend

[Crispin Flowerday]

Further investigations show that when hal is invoked, nothing in
/proc/net is setup yet (seems especially to be a problem for the ipw2200
driver, my other e100 driver works fine).

However, the stuff in /sys/class/net/eth* is setup fine. If I put a tiny
sleep (not a real solution I know) in the classdev.c file just before it
reads /proc/net/wireless everything works fine.

There is some code in classdev.c that just looks for the
/sys/class/net/wireless directory. I don't claim to know why it isn't
used, but if I use that code instead (patch attached) everything works
fine for me.

Perhaps this should be given to the kernel people to work out why there
is this race condition ? I would have thought /proc should be as up to
date as /sys when the notification occurs
