brcmfmac: disable PCIe interrupts before bus reset

2019-11-20T07:45:35Z

Keeping interrupts on could result in brcmfmac freeing some resources and then IRQ handlers trying to use them. That was obviously a straight path for crashing a kernel.

Kalle Valo says: ==================== wireless-drivers-next patches for 5.5 First set of patches for 5.5. The most active driver here clearly is rtw88, lots of patches for it. More quiet on other drivers, smaller fixes and cleanups all over. This pull request also has a trivial conflict, the report and example resolution here: https://lkml.kernel.org/r/20191031111242.50ab1eca@canb.auug.org.au Major changes: rtw88 * add deep power save support * add mac80211 software tx queue (wake_tx_queue) support * enable hardware rate control * add TX-AMSDU support * add NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 support * add power tracking support * add 802.11ac beamformee support * add set_bitrate_mask support * add phy_info debugfs to show Tx/Rx physical status * add RFE type 3 support for 8822b ath10k * add support for hardware rfkill on devices where firmware supports it rtl8xxxu * add bluetooth co-existence support for single antenna iwlwifi * Revamp the debugging infrastructure ==================== Signed-off-by: David S.

brcmfmac: add support for SAE authentication offload

2019-10-04T13:45:51Z

The firmware may have SAE authentication code built-in. This is detected by the driver and indicated in the wiphy features flags. User-space can use this flag to determine whether or not to provide the password material for SAE authentication in the nl80211 CONNECT command.
