kernel: fix Wi-Fi RX instability and bogus MAC address - #127
Merged
Conversation
- Add RFC patches from Richard Acayan (ath10k list, Feb 2026):
- 0016: WCN3990 splits A-MSDUs across multiple HTT in-order
indications; mainline dropped them ("failed to extract amsdu: -11",
rx_confused), collapsing TCP under load (49 kB/s). Persist the
in-order MSDU list in driver state.
- 0017: don't wait for a DELETE_KEY response the firmware never
sends (fixes -ETIMEDOUT/-110 on key removal).
- 0011: the firmware reports a bogus 0e:00:00:00:00:00 MAC that passes
is_valid_ether_addr(), so the socinfo fallback never ran. Also treat
that dummy address as invalid.
Verified on mici: permaddr now 00:0a:f5:xx:xx:xx, throughput
49 kB/s -> 16.8 MB/s (433 Mbps VHT80 rx rate), 20 MB scp both
directions with no amsdu errors, deauths, or key timeouts.

Problem
On the mainline kernel (AGNOS userspace), Wi-Fi collapses under any sustained transfer — a 10 MB scp stalls out and drops the SSH session. Separately, the Wi-Fi MAC address is wrong.
Root causes
failed to extract amsdu: -11,rx_confused), dropping frames and collapsing TCP. Measured 49 kB/s at -36 dBm signal.0e:00:00:00:00:00which passesis_valid_ether_addr(), so patch 0011's socinfo-derived MAC never applied.Changes
0016/0017: RFC patches by Richard Acayan from the ath10k list (1/2, 2/2) — persist the in-order MSDU list in driver state; don't wait for a DELETE_KEY response the firmware never sends (fixes the-110key-removal errors also seen in dmesg). Review so far: style nits only; 2/2 independently confirmed on QCA6174. Draft until the series lands upstream in final form.0011: also treat the0e:00:00:00:00:00firmware dummy as invalid so the socinfo MAC (00:0a:f5+ SoC serial) applies.Verification (on mici)
