Re: [PATCH] wifi: brcmfmac: cfg80211: Handle SSID based pmksa deletion

wpa_supplicant 2.11 broke Wi-Fi on T2 Macs as well, but this patch doesn't seem to be fixing Wi-Fi. Instead, it's breaking it even on older 2.10 wpa_supplicant. Tested by a user on bcm4364b2 wifi chip with a WPA2-PSK [AES] network. dmesg output:

However dmesg outputs more info
