Subject: [PATCH] mac80211: mesh: avoid pointless station lookup
|
|
|
|
In ieee80211_build_hdr(), the station is looked up to build the
|
|
header correctly (QoS field) and to check for authorization. For
|
|
mesh, authorization isn't checked here, and QoS capability is
|
|
mandatory, so the station lookup can be avoided.
