That change was lost in a rebase cleanup for the other changes. It will need further work as there's not only the classic suspend/resume path from the device driver in there but also the "WoWLan" suspend/resume path from the mac80211 level, which, at least for iwlwifi does the actual PCIe transition if I read the code correctly. FreeBSD has no notion of the latter (yet) as we would normally call ieee80211_suspend_all()/ieee80211_resume_all() from the device driver handler directly using our internal notion of the wireless device softc (ic) but even that will only stop/start things and not leave us with the actual call into D3 for LinuxKPI based drivers. In other words to my best knowledge nothing in FreeBSD supports WoWLan just yet and it is just another one thing that somehow needs to be prepared for. I'll look into at least the suspend/resume paths the next days and hopefully will find a way to hook it up to net80211 and LinuxKPI. > Lots of health, > Bjoern > > > [1] https://github.com/freebsd/wireless/tree/bz_wifi_drv_update > > -- Bjoern A.
