Re: Airport driver sleep problem and solution

Derrik Pates spake unto us the following wisdom:

I recently found that, if the Airport card in an iBook I've been running
Linux on was not brought "up" at the time the system was put to sleep (by
putting the lid down), after bringing it back out of sleep, it would no
longer correctly operate until the driver was removed and reloaded -
ifconfig would receive an ENODEV error, and iwconfig would report that the
device had no wireless extensions. I found that the problem is on line 179
of linux/drivers/net/wireless/airport.c (v0.06f, in 2.4.9-benh0), where
the driver only calls "netif_device_attach" if card->open is TRUE - but it
unconditionally calls "netif_device_detach" in the PBOOK_SLEEP_NOW case.
Line 179 should be changed from "else if (card->open)" to just "else", so
that the network device is "reattached" to the networking subsystem.

Spectacular!  I've had this trouble as well, and I solved it my just
leaving my Airport card configured all the time, regardless of whether
I was on a network or not.  I'm glad to see a real fix.  :-)
