Message-ID: <20151202082615.M11952@cdot.in> (raw)
Hi
I want to change MCS rate for ath9k 802.11n config.We are using ath9k driver with debug
enabled and debugfs mounted.
Kernel config options for driver
CONFIG_ATH_COMMON=m
CONFIG_ATH_CARDS=m
CONFIG_ATH_DEBUG=y
CONFIG_ATH5K=m
# CONFIG_ATH5K_DEBUG is not set
CONFIG_ATH5K_PCI=y
CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K_BTCOEX_SUPPORT=y
CONFIG_ATH9K=m
CONFIG_ATH9K_PCI=y
# CONFIG_ATH9K_AHB is not set
CONFIG_ATH9K_DEBUGFS=y
CONFIG_ATH9K_MAC_DEBUG=y
CONFIG_WIRELESS=y
CONFIG_WEXT_CORE=y
CONFIG_WEXT_PROC=y
CONFIG_CFG80211=m
# CONFIG_NL80211_TESTMODE is not set
# CONFIG_CFG80211_DEVELOPER_WARNINGS is not set
CONFIG_CFG80211_REG_DEBUG=y
# CONFIG_CFG80211_CERTIFICATION_ONUS is not set
# CONFIG_CFG80211_DEFAULT_PS is not set
CONFIG_CFG80211_DEBUGFS=y
CONFIG_CFG80211_INTERNAL_REGDB=y
CONFIG_CFG80211_WEXT=y
# CONFIG_LIB80211 is not set
CONFIG_MAC80211=m
CONFIG_MAC80211_HAS_RC=y
# CONFIG_MAC80211_RC_PID is not set
CONFIG_MAC80211_RC_MINSTREL=y
CONFIG_MAC80211_RC_MINSTREL_HT=y
CONFIG_MAC80211_RC_DEFAULT_MINSTREL=y
CONFIG_MAC80211_RC_DEFAULT="minstrel_ht"
CONFIG_MAC80211_MESH=y
CONFIG_MAC80211_LEDS=y
CONFIG_MAC80211_DEBUGFS=y
# CONFIG_MAC80211_MESSAGE_TRACING is not set
# CONFIG_MAC80211_DEBUG_MENU is not set
# CONFIG_WIMAX is not set
CONFIG_RFKILL=m
CONFIG_RFKILL_LEDS=y
CONFIG_RFKILL_INPUT=y
We are getting /sys/kernel/debug/ieee80211/phy0 with contents
ath9k hwflags netdev:wlan0 queues
rts_threshold total_ps_buffered
fragmentation_threshold keys netdev:wlan0.sta1 rc
short_retry_limit user_power
ht40allow_map long_retry_limit power reset
statistics wep_iv
We are not getting /sys/kernel/debug/ath9k for changing mcs-rate as
echo 15 > /sys/kernel/debug/ath9k/phy0/mcs-rate
We are using kernel 3.10.0
Kindly help us how to change the MCS rate in this case.
