Tested on a Netgear A9000 (MT7925U, USB), Linux 7.2.6, firmware
20260813113118, morrownr/mt76 at ce4ee3e, against a two-link mt7996
AP MLD on 5745 and 6135 MHz.

Your STA_REC_MLD capture reproduces here. Without v2 the AP got
nothing on 5745 in any run I checked. With v2, 5745 carried traffic
under the scan load from my earlier report:

                                      stock          v2
  scan load, 600 s, mean per ~10 s    249, 267 MB    801, 837 MB
  scan load, 600 s, lowest ~10 s      126 B, 33 MB   643, 687 MB
  scan load, share of bytes on 5745   0              about 60%
  scanning off, share on 5745         0              0

Stock dipped under that load but did not stall for good this time, so
the stall result is Jonas's run, not mine.
