With RTL8811AU, before: 30 Mbps, after: 224 Mbps. The out-of-tree driver uses aggregation size of 7 in USB 3 mode, but that doesn't work here. rtw88 advertises support for receiving AMSDU in AMPDU, so the AP sends larger frames, up to ~5100 bytes. With a size of 7 RTL8812AU frequently tries to aggregate more frames than will fit in 32768 bytes. Use a size of 6 instead.
