[PATCH 24/18] iwlwifi: don't access mac80211's AMPDU state machine

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There really is no need, at worst ieee80211_start_tx_ba_session
will log a message when debugging is enabled, and poking such
internals of mac80211 definitely doesn't belong into an RC
algorithm.
