commit d5f1a9f574f9144c86450440ff495e471735ae26 Author: Bjoern A. Zeeb <[email protected]> AuthorDate: 2026-02-04 22:39:01 +0000 Commit: Bjoern A. Zeeb <[email protected]> CommitDate: 2026-02-26 23:01:45 +0000 LinuxKPI: 802.11: make sure we are scheduled before wake_tx_queue() If we are not scheduled before calling wake_tx_queue() packets may never go out, which at first will look like EAPOL fails (as wpa_supplicant suggest possibly with a wrong key). Using monitor mode it will be clear what is going on. Pass a flag down to wake_tx_queue() to call ieee80211_schedule_txq() in case (*wake_tx_queue)() is supported or not, which solves the problem for the lkpi_80211_txq_tx_one() which was failing.
