Agreed. Tested chip set for this patch:

Bitterblue's bench (per the commit body):
  RTL8852B: RTL8832BU
  RTL8852C: RTL8832CU

My side (per the v2 cover letter matrix):
  RTL8852A: D-Link DWA-X1850 A1 (8852AU)
  RTL8852A: D-Link DWA-X1850 B1 (8852AU)
  RTL8852B: BrosTrend AX1L (8832BU)
  RTL8852B: BrosTrend AX4L (8832BU)
  RTL8852C: BrosTrend AX8L (8832CU)
  RTL8852C: EDUP AXE5400 (8832CU)

v3 will gate on RTL8852A / RTL8852B / RTL8852C. RTL8851B stays out
because no RTL8851B variant has USB 3 hardware (per the in-patch
comment), so there is nothing to switch to.

WiFi 7 in rtw89 appears to be exclusively BE-generation as far as
I am aware (RTL8922A, RTL8922D). v2's AX-gen code (R_AX_PAD_CTRL2
writes) would not execute for BE-gen chips, so no WiFi 7 chip
appears testable for this patch by construction.
