[PATCH rtw-next 08/10] wifi: rtw89: wow: use MLD address in WoWLAN ARP replies for MLO stations

[Ping-Ke Shih <pkshih@realtek.com>]

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

Currently, WoWLAN ARP replies for MLO stations use the link address in
the ARP hardware address fields.

As a result, peers may learn the link address from the ARP reply and
use it as the destination address for subsequent traffic. Some APs may
not forward frames addressed to the link address, causing connectivity
issues.

Use the MLD address instead when generating WoWLAN ARP replies so peers
learn the correct address for MLO stations.
