Perhaps the behaviour is different with hw.pci.do_power_nodriver=3
commented out but I fail to successfully switch from using iwm to
iwlwifi.
I'll leave hw.pci.do_power_nodriver=3 commented out to make it easier on
future testing.
I saw your mail about how busy you've been so thanks for all the
continuing efforts of trying to improve WiFi on FreeBSD.
I wish you and all a very happy New Year (6 hours to go for me so I'm going to
spend time with my wife now) and hopefully we can continue this in the
new year.
Happy New Year everybody
