Ben,

IIRC mesh support was validated in qca988x in VHT mode while ago.  Either it could
be regression in driver/fw or lede mac80211 package.

1) Could you please try plain backports in lede w/o applying ath10k patches.
     I do see 160MHz support in LEDE.
2) There are some peer stats dump from your earlier log. Disable peer stats 
     by "peer_stats" debugfs.
3) Please confirm the behavior with older firmware revisions.
4) use iw to bring up open mesh to rule out wpa_s config
