[PATCH 2/2] wcn36xx: fix the mesh STA for rejoin

Nope. But I remember that last time we try to delete the peer mesh STA
and add it back (in firmware) without doing anythings on mac80211. We
seems to lost connectivity with the peer mesh STA after adding back to
firmware.

Yes, for mesh mode, we have peer link timer to monitor the peer mesh
STA in mac80211. Once we don't receive any beacon from the peer mesh
STA (default 1800 seconds), the peer mesh STA will be deleted.

Did you try to delete the peer mesh STA in firmware and add it back?
Does this work?
