Subject: [PATCH] ath10k: Ensure txrx-compl-task is stopped when cleaning

|
htt-tx.
|
||||||
|
|
||||||
|
Otherwise, the txrx-compl-task may access some bad memory?

Subject: [PATCH] ath10k: Ensure peer_map references are cleaned up.
|
||||||
|
|
||||||
|
While debugging OS crashes due to firmware crashes, I enabled
|
||||||
|
kasan, and it noticed that peer objects were being used-after-freed.
|
||||||
|
|
||||||
|
Looks like there are two places we could be leaving stale references
|
||||||
|
in the peer-map, so clean that up.

Subject: [PATCH] ath10k: Clean up peer when sta goes away.
|

If WMI and/or firmware has issues removing the peer object,
|

then we still need to clean up the peer object in the driver.

Subject: [PATCH] ath10k: fix CCK h/w rates for QCA99X0 and newer chipsets
|
||||||
|
|
||||||
|
CCK hardware table mapping from QCA99X0 onwards got revised.
|
||||||
|
The CCK hardware rate values are in a proper order wrt. to
|
||||||
|
rate and preamble as below
|
||||||
|
|
||||||
|
ATH10K_HW_RATE_REV2_CCK_LP_1M = 1,
|
||||||
|
ATH10K_HW_RATE_REV2_CCK_LP_2M = 2,
|
||||||
|
ATH10K_HW_RATE_REV2_CCK_LP_5_5M = 3,
|
||||||
|
ATH10K_HW_RATE_REV2_CCK_LP_11M = 4,
|
||||||
|
ATH10K_HW_RATE_REV2_CCK_SP_2M = 5,
|
||||||
|
ATH10K_HW_RATE_REV2_CCK_SP_5_5M = 6,
|
||||||
|
ATH10K_HW_RATE_REV2_CCK_SP_11M = 7,
|
||||||
|
|
||||||
|
This results in reporting of rx frames (with CCK rates)
|
||||||
|
totally wrong for QCA99X0, QCA4019. Fix this by having
|
||||||
|
separate CCK rate table for these chipsets with rev2 suffix
|
||||||
|
and registering the correct rate mapping to mac80211 based on
|
||||||
|
the new hw_param (introduced) 'cck_rate_map_rev2' which shall
|
||||||
|
be true for any newchipsets from QCA99X0 onwards
