Add an ADDBA_OFFLOAD capability for wifi devices manage Tx block ack sessions entirely in firmware. This will be used by iwx(4). |

Add support for Tx aggregation to the iwx(4) driver. Throughput goes up to 100 Mbit/s under ideal conditions. This is mostly working and stable, however rare occasional hangs may occur where the device stops giving us interrupts for reasons which are not yet understood. In such cases ifconfig down/up will recover the interface. Regardless, this code seems to be stable enough for remaining issues to be resolved in-tree. My working assumption is that the remaining issues were always present but only trigger under increased load when firmware is driven with Tx agg enabled. Feedback is welcome, especially if stability issues turn out to be worse than expected! As usual, please enable "ifconfig iwx0 debug" when reporting issues. Tests on ax200/ax201: myself, dv, hrvoje, Stefan Hagen, kevlo, Eric Auge, mlarkin, jmc, Mark Patruck Of which only me and jmc have reported seeing a small amount of hangs during continuous usage over about 2 weeks. |

Revert ieee80211_proto.c r1.97 (cvs commit ID 8vKZsdvvkjTr5BG5). My assumption that frames which are buffered on the power save queue were already encrypted was wrong. And the issue which this change intended to fix is still present (reported by Mikolaj Kucharski). |

Reset the Tx timer when iwx(4) firmware sends a BA notification. When multiple frames are sent in a batch on a Tx aggregation queue our current firmware version does not provide the IWX_TX_CMD notification. Older versions used to provide this (as observed on iwm(4) devices), but our current firmware only sends IWX_BA_NOTIF. This means we need to reset the Tx timer upon BA_NOTIF in order to avoid a bogus "device timeout" trigger from our watchdog handler. Do this as soon as the BA notification has been validated. |
