   3 Subject: [PATCH] mac80211: minstrel: skip memset on station rate control
   4  data
   5
   6 With legacy minstrel support gone, there is no need to clear the data on
   7 capability updates anymore. The supported flags are fully re-initialized,
   8 and previous rate table statistics can be preserved.
