-Subject: [PATCH] mac80211: minstrel_ht: reduce unnecessary rate probing
- attempts
-
-On hardware with static fallback tables (e.g. mt76x2), rate probing attempts
-can be very expensive.
-On such devices, avoid sampling rates slower than the per-group max throughput
-rate, based on the assumption that the fallback table will take care of probing
-lower rates within that group if the higher rates fail.
-To make this work, this also fixes a wrong initialization in the previously
-unused per-group sorted rate array.
-To further reduce unnecessary probing attempts, skip duplicate attempts on
-rates slower than the max throughput rate.
