Got a chance to play with new WiFi hardware:
BananaPi BPI-R4, mt76-based WiFi 7 7/802.11be access point.

Support in mainline OpenWRT is now good enough to "just work".
No MLO support yet, WIP.

Client is a Intel BE200 M.2 card, 2x2 MIMO.
Was able to get MCS13 (aka 4096QAM) working at 320 MHz, which results in a 5.7Gbit/s PHY rate and ~3Gbit/s of actual TCP throughput.

BE200 drivers on Linux still seem a bit wonky, "only" 2 Gbit/s on Linux.
Windows 11 works as expected.
