Tested on an ASUS Zenbook A16 (UX3607OA, Snapdragon X2 Elite) with
the on-board QCC2072, on v7.4-rc1 plus c752394249f8, 02121aa4a012 and
1e678e37ff13 from ath.git and out-of-tree Glymur platform/board
patches, without Miaoqing's "fix MLO 4-way handshake timeout on
QCC2072". All 11 applied as posted.

A Wi-Fi 7 MLO SSID (SAE, PMF required, 2.4+5+6 GHz) that used to fail
with reason 15 connects as MLO with three links: 12 of 12
connect/disconnect cycles and 5 of 5 rejoins after s2idle resume,
ping OK each time. Non-MLO 5 GHz is unaffected. The firmware sends
PEER_EXTENDED, so the host allocation in 8/11 was not exercised.

Tested-on: QCC2072 hw1.0 PCI WLAN.COL.1.0.c2-00277-QCACOLSWPL_V1_TO_SILICONZ-1

AI coding assistants helped run these tests and draft this reply; the
results are from the hardware runs.
