Hi Alessio,

On the TX gain: that fits. In the basement (-70 dBm) index 64 carries no HT frame at all, index 20 works, index 0 is worse again. The reset value was just far too quiet. I now use index 20, inside the range the stock power loop ran at here (0x14–0x26), until I have power control.

RX aggregation works too. It only needed accepting the session in ampdu_action; the microcode deaggregates and sends the block acks. Both directions aggregated: about 30 Mbit/s up and 20 down at -70 dBm, against 13 and 10 at legacy rates.

On the RCAL timeout: that run was your unmodified head without my logging, so no added delays. I can rerun it and send the full dmesg.

On the PHY words: yes, these are writes of the hybrid 6.30.223 wl on the MacBookAir6,1, from my MMIO trace at 2.4 GHz: 0x1739 = 0, 0x016b = 0, 0x0175 = 0, 0x03c4 = 0x0668, and in channel setup 0x0197 = 0x0014, 0x0198 = 0x0010. Bluetooth is plausible, the board has BTCOEXIST set.

Thanks, Andreas
