Hi Ping-Ke,

Just a quick update to keep you informed -- no rush on anything.

My kernel updated from 6.19.7 to 6.19.9, which wiped the previously
installed out-of-tree modules. I rebuilt and reinstalled both patches:

  1. The v2 DMI quirk (main.h + pci.c) disabling ASPM and LPS Deep
     Mode for the HP P3S95EA#ACB SKU.
  2. The rate validation patch (rx.c) clamping out-of-bounds rate
     values before they reach mac80211.

Both patches apply cleanly and the system remains fully stable on
6.19.9. The DMI quirk is confirmed active via sysfs (disable_aspm=Y,
disable_lps_deep=Y) with no manual modprobe overrides.

I am looking forward to your formal patch for the VHT NSS=0 issue and
will provide a Tested-by tag as soon as it arrives. Thank you again
for all your work and patience throughout this process.

Best regards,
Oleksandr Havrylov
