Comment 13 for bug 994739

This is a better patch, which fixes the driver_wext in wpasupplicant when using broadcom's wl driver and shouldn't have effect when using any other underlying wifi driver, this is adapted from here to the current version of wpasupplicant in ubuntu:

With this patch, the time to wait after a suspend when using networkmanager is around 12 seconds, i think it's an acceptable alternative if the patch gets included in ubuntu's wpasupplicant package.
