Agreed with all the above. I'll discard the driver patch.

There are two other things I can think of:

1. make sure wpa_supplicant is shut down before ifconfig ethX down, and
restart it on resume.

>From the data you've provided it looks like your distribution brings the
device down, but may leave wpa_supplicant running. I've noticed that
every time wpa_supplicant shuts down it removes most configuration
settings. Or has that changed?

2. Does the driver need to send a dissociation event (or something) to
userspace on ifconfig down?
