Subject: nl80211: clarify packet statistics descriptions
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8d791361a4698ca6f01c361a47b39b30d26bf66c;p=linux-beck.git

nl80211: clarify packet statistics descriptions

The current statistics we keep aren't very clear, some are on
MPDUs and some on MSDUs/MMPDUs. Clarify the descriptions based
on the counters mac80211 keeps.
