[PATCH] ieee80211: Provide generic get_stats implementation
bcm43xx and ipw2100 currently duplicate the same simplistic get_stats handler. Additionally, zd1211rw requires the same handler to fix a bug where all stats are reported as 0. This patch adds a generic implementation to the ieee80211 layer, which drivers are free to override. Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.
