Subject: [PATCH] [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.
