Description Andriy Voskoboinyk freebsd_committer freebsd_triage 2017-02-26 00:29:03 UTC 
Since r287197 there are no device entries visible via ifconfig(8); MAC address can be overridden for wlan(4) interface only:

ifconfig wlan0 create wlandev iwn0 ether 00:21:70:da:ae:37 ssid my_router up

or via wlanaddr parameter (broken on 11.0-RELEASE?):

ifconfig wlan0 create wlandev iwn0 wlanaddr 00:21:70:da:ae:37 ssid my_router up

rc.conf(5) config:

ifconfig_bge0="up"
wlans_iwn0="wlan0"
ifconfig_wlan0="ether 00:21:70:da:ae:37 WPA"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto failover laggport bge0 laggport wlan0 DHCP"
Comment 1 Taras Korenko 2017-02-26 22:09:42 UTC 
Since "there are no device entries visible via ifconfig(8)", the ifconfig-way, described in "30.3.2. Quick Start, 2. Identify the wireless adapter" [1], is no longer valid for newer versions of OSes.
  I guess we should advise looking through plain old dmesg(8) for wireless adapters detected by the kernel, as it is applicable to a broader range of versions of OSes.

Comment 2 Ben Woods freebsd_committer freebsd_triage 2017-02-26 22:53:11 UTC 
The new way to discover available wireless interfaces is to run:
$ sysctl net.wlan.devices
Comment 3 Taras Korenko 2017-02-26 23:05:18 UTC 
Afaik, "sysctl net.wlan.devices" is available in >= FreeBSD11.

The question about applicability of 'wlandebug' [1] is left open.

Attachment #180516 [details] is no longer actual, this (sub)case was fixed in bug #214586 .

Is this still relevant following https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211436 ?

Guessing not, please reopen if I'm wrong.
