The legacy minstrel code is essentially unmaintained and receives only very little testing. In order to bring the significant algorithm improvements from minstrel_ht to legacy clients, this patch adds support for OFDM rates to minstrel_ht and removes the fallback to the legacy codepath. This also makes it work much better on hardware with rate selection constraints, e.g. mt76. Changes in v3: - add cover letter - fix uninitialized stack variable - add extra patch to fix significant rounding error in tpt calculation Changes in v2: - fix using legacy-rates overhead in tpt calculation Felix Fietkau (9): mac80211: minstrel_ht: clean up CCK code mac80211: minstrel_ht: add support for OFDM rates on non-HT clients mac80211: remove legacy minstrel rate control mac80211: minstrel_ht: remove old ewma based rate average code mac80211: minstrel_ht: improve ampdu length estimation mac80211: minstrel_ht: improve sample rate selection mac80211: minstrel_ht: fix max probability rate selection mac80211: minstrel_ht: increase stats update interval mac80211: minstrel_ht: fix rounding error in throughput calculation net/mac80211/Makefile | 2 - net/mac80211/rc80211_minstrel.c | 574 --------------------- net/mac80211/rc80211_minstrel.h | 184 ------- net/mac80211/rc80211_minstrel_debugfs.c | 172 ------ net/mac80211/rc80211_minstrel_ht.c | 560 +++++++++++++------- net/mac80211/rc80211_minstrel_ht.h | 96 +++- net/mac80211/rc80211_minstrel_ht_debugfs.c | 57 +- 7 files changed, 482 insertions(+), 1163 deletions(-) delete mode 100644 net/mac80211/rc80211_minstrel.c delete mode 100644 net/mac80211/rc80211_minstrel.h delete mode 100644 net/mac80211/rc80211_minstrel_debugfs.c -- 2.28.0
