#3222: libbsd: WiFi Support needs rc.conf integration
--------------------------------+------------------------------
 Reporter:  Christian Mauderer  |      Owner:  (none)
     Type:  enhancement         |     Status:  new
 Priority:  normal              |  Milestone:  Indefinite
Component:  network/libbsd      |    Version:  5
 Severity:  normal              |   Keywords:  libbsd WiFi WLAN
--------------------------------+------------------------------
 Currently WLAN is still only poorly integrated into libbsd. A number of
 manual commands are necessary to create a WLAN device.

 FreeBSD supports rc.conf lines like the following one for setting up a
 WLAN device (see
 [https://www.freebsd.org/cgi/man.cgi?query=rc.conf&manpath=FreeBSD+12-current
 rc.conf(5) section ''network_interfaces'']):

 {{{
 wlans_rtwn0="wlan0"
 ifconfig_wlan0="DHCP"
 }}}

 The rtems-libbsd should support this notation too.

 Problematic in this context is that all currently supported WLAN devices
 are USB devices. These devices need some time to enumerate or can even be
 hot plugged. Therefore they might not be available during the first
 parsing of rc.conf.

 We need a method to handle such hot plugged events. For that it will be
 necessary to keep relevant information from the rc.conf available.
