Sorry to jump in so late, but I just got a chance to compile this a couple
days ago.

Is this vap code the same one that was committed?  Something seems
to have confused my wireless card a great deal, possibly in the initialization
steps.  I have a broadcom chip that will hopefully eventually be supported
by bwi, but I have been using ndis otherwise.
With a recompiled ndisulator driver, ifconfig up-ing the interface causes
the machine to panic; a vanilla ifconfig does not, but clearly the driver
is confused.

bwi attaches successfully, but complains about antenna gain [1]; not
sure if this is why it doesn't work.

Before I start debugging bwi, though I would like to get a working
internet connection again.

This is what the odd ifconfig output is:
prolepsis# ifconfig ndis0
ndis0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 2290
        ether 00:90:4b:2d:46:ce

I have a dump of the panic when I ifconfig ndis0 up, if you want
me to poke around at it. The relevant line may be:
#10 0xc4570960 in ndis_setstate_80211 (sc=0xc45ad000)
    at /usr/src/sys/modules/if_ndis/../../dev/if_ndis/if_ndis.c:2205

Thanks, and sorry if this has already been fixed -- it's hard to csup without
a working network connection.
