Subject: [PATCH 1/2] wifi: rtw89: support WoWLAN mode for 8852be
Date:   Mon, 10 Apr 2023 13:34:37 +0800

From: Chin-Yen Lee <timlee@realtek.com>

To support WoWLAN mode for 8852be, we add one PLE quota setting and
WoWLAN stub, which shows that supported WLAN events include receiving
magic packet, rekey packet and deauth packet, and disconnecting from AP.
