iwm(4) broken on latest -current kernel

[Kevin Bloom <ktnb%netbsd.org@localhost>]

Hi all,

I recently pulled down the latest changes (yesterday) for src and
xsrc and built everything. It appears that iwm(4) is no longer
working correctly. It will connect to my wifi for a short amount
of time (~30 seconds) then it will disconnect. It keeps doing this
over and over. During the 30 seconds it's connected ifconfig(1)
shows "no network" for the status. Attemping to ping(1) during that
time results in an error as well. Reverting to my 11.99.3 kernel
fixes the issue for now, enabling me to send this.

If I remember correcly there were some changes to iwm(4) recently.
I haven't the time to get more information as I've leaving for a
business trip but I can attempt to get more information when I'm
back. Just wanted to make this issue known!

Thanks,
