Implements - Frequency offset calibration - Better fallback rates - Aggregation - GRO Tested on WNDA4100 RT3593, 5 GHz with iperf3 patch before after TX RX TX RX 2 crystal calibration 27.7 31.6 28.5 69.7 3 MCS16 to MCS8 TX status 27.0 70.0 29.4 70.0 5 RX bulk aggregation 30.5 67.8 30.5 80.9 7 threaded NAPI with GRO 30.5 80.9 30.5 161.7 RT3070 did not have any visible change for both TX and RX. Patch 5 added WARN_ON_ONCE to get_rx_seg_len, but it will always trigger due to a bug due to USB data toggle. The fix will be sent in another patch. Changes in v3: - Crystal calibration: save the frequency offset of the beacons in rt2x00lib_rxdone_skb() instead of fill_rxdone, through rxdesc - RX aggregation: enable it for usb_maxpacket >= 512 - GRO: Add locking and reference mt76 on how it is done Changes since v2: - Correct the link tuner start and stop conditions - Extend fallback and MCS retry calculation to all devices with 3 TX chains - Remove TX AMSDU and fast-xmit Ho Jie Feng (7): wifi: rt2x00: start the link tuner when an interface is added wifi: rt2800: calibrate the crystal of RT3593 with the beacons wifi: rt2800: make MCS 16 fall back to MCS 8 on devices with 3 TX chains wifi: rt2800: don't report an A-MPDU length to minstrel_ht wifi: rt2800usb: enable RX bulk aggregation wifi: rt2800: support A-MSDU in A-MPDU wifi: rt2x00usb: use a threaded NAPI with GRO for RX drivers/net/wireless/ralink/rt2x00/rt2800.h | 1 + .../net/wireless/ralink/rt2x00/rt2800lib.c | 89 +++++++++- .../net/wireless/ralink/rt2x00/rt2800lib.h | 1 + .../net/wireless/ralink/rt2x00/rt2800usb.c | 33 +++- .../net/wireless/ralink/rt2x00/rt2800usb.h | 6 + drivers/net/wireless/ralink/rt2x00/rt2x00.h | 37 ++++- .../net/wireless/ralink/rt2x00/rt2x00dev.c | 152 ++++++++++++++---- .../net/wireless/ralink/rt2x00/rt2x00lib.h | 2 + .../net/wireless/ralink/rt2x00/rt2x00link.c | 10 ++ .../net/wireless/ralink/rt2x00/rt2x00mac.c | 13 ++ .../net/wireless/ralink/rt2x00/rt2x00mmio.c | 2 +- .../net/wireless/ralink/rt2x00/rt2x00queue.h | 5 + .../net/wireless/ralink/rt2x00/rt2x00usb.c | 62 +++++-- 13 files changed, 365 insertions(+), 48 deletions(-) base-commit: 3c311bf321442d4c4f452a1a08bc9efce242a1f9 -- 2.53.0
