The following patches:
* 972-ath10k_fix-crash-due-to-wrong-handling-of-peer_bw_rxnss_override-parameter.patch
* 973-ath10k_fix-band_center_freq-handling-for-VHT160-in-recent-firmwares.patch
are replaced by this commit in the upstream kernel:
* 3db24065c2c8 ("ath10k: enable VHT160 and VHT80+80 modes")
The following patches were applied upstream:
* 001-rt2800-enable-MFP-support-unconditionally.patch
* 090-wireless-Use-linux-stddef.h-instead-of-stddef.h.patch
The rtw88 driver is now split into multiple kernel modules, just put it
all into one OpenWrt kernel package.
rtl8812au-ct was patched to compile against the mac80211 from kernel
5.8, but not runtime tested.
Add a patch which fixes ath10k on IPQ40XX, this patch was send upstream
and fixes a crash when loading ath10k on this SoC.

|
|
+ * There is a bug with in-firmware BSS management. When adding virtual
|
|
+ * interface brcmfmac first tells firmware to create new BSS and then
|
|
+ * it creates new struct net_device.
|
|
+ *
|
|
+ * If creating/registering netdev(ice) fails, BSS remains in some bugged
|
|
+ * state. It conflicts with existing BSSes by overtaking their auth
|
|
+ * requests.
|
|
+ *
|
|
+ * It results in one BSS (addresss X) sending beacons and another BSS
|
|
+ * (address Y) replying to authentication requests. This makes interface
|
|
+ * unusable as AP.
|
|
+ *
|
|
+ * To workaround this bug we may try to guess if register_netdev(ice)
|
|
+ * will fail. The most obvious case is using interface name that already
|
|
+ * exists. This is actually quite likely with brcmfmac & some user space
|
|
+ * scripts as brcmfmac doesn't allow deleting virtual interfaces.
|
|
+ * So this bug can be triggered even by something trivial like:
|
|
+ * iw dev wlan0 delete
|
|
+ * iw phy phy0 interface add wlan0 type __ap
