Hello,
I see that setting the essid of a wireless card
(by iwconfig eth1 essid homenet)
triggers scanning;
namely , it calls ieee80211softmac_assoc_work() method which in
turn calls ieee80211softmac_start_scan().
I use zd1211 driver which works with the softmac layer
of the last git kernel.

Something like this would handle errors better, but introduce possible
problems for drivers that call register_netdevice with irq's disabled.
There was some comment about racing with linkwatch, but don't see how
that could happen during creation.
For 2.6.18?

Yeah, I realise that. I've tried booting windows which behaves exactly

Bringing down a port also masks off the status and other IRQ's
needed for device to function due to missing paren's.
