Testing on MacMook Air M1 (dmesg below) with
bwfm0 at pci1 dev 0 function 0 "Broadcom BCM4378" rev 0x03: msi

I don't see any regression. Generaly, I used to see drops and
reconnects on various eduroam networks

 bwfm0: Associated with 00:00:00:00:00:00
 bwfm0: Authentication with 00:00:00:00:00:00 timed out.
 bwfm0: No network configuration found for the current AP
 bwfm0: CTRL-EVENT-DISCONNECTED bssid=f4:f2:6d:53:e8:98 reason=3 locally_generated=1
 bwfm0: CTRL-EVENT-TERMINATING 

I will let it run like this for a couple of days.

	Thanks,
