Hi all,

I open a new thread for this one: During the last weeks I have seen 
connection losses for 30+ minutes, sometimes even hours or just now even 
forever (IWD HEAD with v2 OWE / BSS selection patches). Driver is 
brcmfmac (NXP 6.1.36 kernel) and chip is BCM4339 (Laird LWB5).

It happens in a) single router environment (WPA2-PSK; Touchstone 
TG3442DE), and b) router + repeater environment (WPA2 CCMP; Fritz!Box + 
Fritz!Repeater), and maybe also in the WPA3 OWE Transition network 
(yesterday lost a connection again).

We have 100% reproducable builds, test environments (testing sites), and 
web socket-based telemetry. Thus my feeling is, there is still something 
wrong with the BSS selection (maybe blacklisting)! Of course this can 
also be something about the driver (brcmfmac) or firmware (roaming?). Or 
can this be about IPv6 disabled (my configuration below)?

This is really really serious, I (still) lose connections to devices!

I will investigate further and provide logs later today, if possible.
