hi,
are the mtd memory-only partitions or written to emmc? on second case i need to check if anything else is affected (preloader,head0,head1,atf,uboot,…,existing partitions BPI-BOOT/BPI-ROOT)
thank you for the firmware-files…i will try this instead 
since it is the linux way 
for the mac/cfg80211 patches, second link i found no related to this before…first one i’m searching the patches needed…have not seen the ones i got from patchwork
IEEE80211_KEY_FLAG_GENERATE_MMIE => https://patchwork.kernel.org/patch/11045085/
needs IEEE80211_KEY_FLAG_NO_AUTO_TX for applying => https://patchwork.kernel.org/patch/10860335/
“NLA_POLICY_MAX(NLA_U32, NUM_NL80211_KEYTYPES - 1)” needs this: https://patchwork.kernel.org/patch/10623157/
nl80211_ftm_responder_policy this needs this https://patchwork.kernel.org/patch/10608889/
NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 => https://patchwork.kernel.org/patch/11179155/
last cannot be applied due to missing rtw88 driver…
if i apply first patch manually (ignoring the missing BIT9 value) i get undeclared IEEE80211_HW_TX_STATUS_NO_AMPDU_LEN (https://patchwork.kernel.org/patch/10767013/) which depends on string “MMPDUs on station interfaces” i don’t find any Patch on Patchwork…
i guess it’s easier to integrate in 5.4…seems 5.4 does not need any additional Patches only some small fixes…
driver compiles without any issues…i guess i need only dts-changes now and then can test
btw. i suggest renaming the CONFIG-Symbol as MT7622 is not only a wifi-symbol and may collide with some other symbol…maybe something like MT7622_WIFI or similar

but hostapd gives me this:

starting like this:
ip addr add 192.168.19.1/24 dev wlan0
hostapd -dd /etc/hostapd/hostapd.conf
, and you can also compare the performance after porting.
since it is the linux way
