mac80211: Tx frame latency statistics
Measure TX latency and jitter statistics per station per TID. These Measurements are disabled by default and can be enabled via debugfs. Features included for each station's TID: 1. Keep count of the maximum and average latency of Tx frames. 2. Keep track of many frames arrived in a specific time range (need to enable through debugfs and configure the bins ranges) Signed-off-by: Matti Gottlieb <matti.gottlieb@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
