[PATCH] fix /sys/class/net/<if>/wireless without dev->get_wireless_stats
dev->get_wireless_stats is deprecated but removing it also removes wireless
subdirectory in sysfs. This patch puts it back.
akpm: I don't know what's happening here. This might be appropriate as a
2.6.15.x compatibility backport. Waiting to hear from Jeff.
