https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D192641 --- Comment #3 from commit-hook@freebsd.org --- A commit references this bug: Author: avos Date: Wed Jan 16 12:33:07 UTC 2019 New revision: 343094 URL: https://svnweb.freebsd.org/changeset/base/343094 Log: iwn(4): (partially) rewrite A-MPDU Tx path Generic Tx stats fixes: - do not try to parse "aggregation status" for single frames; send them to iwn_tx_done() instead; - try to attach mbuf / node reference pair to reported BA events; allows to fix reported status for ieee80211_tx_complete() and ifnet count= ers (previously all A-MPDU frames were counted as failed - see PR 210211); requires few more firmware bug workarounds; - preserve short / long retry counters for wlan_amrr(4) (disabled for now - causes significant performance degradation). - Add new IWN_DEBUG_AMPDU debug category. - Add one more check into iwn_tx_data() to prevent aggregation ring overflow. - Workaround 'seqno % 256' !=3D 'current Tx slot' case (until D9195 is not in the tree). - Improve watchdog timer updates (previously watchdog check was omitted when at least one frame was transmitted). - Stop Tx when memory leak in currently used ring was detected (unlikely to happen). - Few other minor fixes. Was previously tested with: - Intel 6205, STA mode (Tx aggregation behaves much better now). - Intel 4965AGN, STA mode (still unstable).
