Subject: ath10k: setup rts/frag thresholds upon vdev creation
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=679c54a67141fb12fd579c6097ebfab4cecf0043;p=linux-beck.git

ath10k: setup rts/frag thresholds upon vdev creation

mac80211 configures rts/frag thresholds per-hw not
per-vif. ath10k FW expects those values to be set
per-vdev (i.e. per-vif).

ath10k should now respect rts/frag thresholds set
before a given interface was brought up.
