You can use the link address now, due to commit 6df2810ac9a9 ("wifi: cfg80211: Allow MLO TX with link source address").
The pointed commit changes not helpful in external authentication case due to WDEV won't have link addresses information when external authentication triggered. The link addresses in WDEV gets updated only after association during connect response processing.
The PASN privacy thing seems something that would be desirable also for mac80211, how would you think it would work there? Also for hwsim testing I guess :)
Need to check what additional changes needed in mac80211 to support this feature. I will check and post required mac80211 changes in v2 series.

Not sure that's better though :)
sure, will do required changes in v2 series - veeru
