This patchset adds support for estimation of the ack timeout (dynack) in ath9k driver. Ath9k dynack computes the ack timeout based on ack frame RX timestamp, TX frame timestamp and frame duration.
Ath9k dynack has been tested in indoor environment using AR9223 chipset (running 3.15.3 kernel) configured as AP and using AR9280 chipset (running 3.16.0-rc3) configured as STA. Ath9k dynack needs to be tested on a long distance link in outdoor environment. Lorenzo Bianconi (10): ath9k: export methods related to ack timeout estimation ath9k: add duration field to ath_tx_status ath9k: add dynamic ack timeout estimation ath9k: add config for (en|dis)abling ack timeout estimation ath9k: do not overwrite ack timeout estimation ath9k: add sampling methods for (tx|rx) timestamp ath9k: enable control frame reception ath9k: add debugfs support for dynack ath9k: disable dynack algorithm when coverage class is set ath9k: add ath_node linked list drivers/net/wireless/ath/ath.h | 2 + drivers/net/wireless/ath/ath9k/Kconfig | 7 + drivers/net/wireless/ath/ath9k/Makefile | 3 + drivers/net/wireless/ath/ath9k/ar9002_mac.c | 7 + drivers/net/wireless/ath/ath9k/ar9003_mac.c | 9 + drivers/net/wireless/ath/ath9k/ath9k.h | 3 + drivers/net/wireless/ath/ath9k/debug.c | 82 ++++++++ drivers/net/wireless/ath/ath9k/dynack.c | 293 ++++++++++++++++++++++++++++ drivers/net/wireless/ath/ath9k/dynack.h | 81 ++++++++ drivers/net/wireless/ath/ath9k/hw.c | 16 +- drivers/net/wireless/ath/ath9k/hw.h | 7 + drivers/net/wireless/ath/ath9k/mac.h | 1 + drivers/net/wireless/ath/ath9k/main.c | 11 ++ drivers/net/wireless/ath/ath9k/recv.c | 7 +- drivers/net/wireless/ath/ath9k/xmit.c | 5 + 15 files changed, 530 insertions(+), 4 deletions(-) create mode 100644 drivers/net/wireless/ath/ath9k/dynack.c create mode 100644 drivers/net/wireless/ath/ath9k/dynack.h -- 1.9.1 _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
