Description Slawomir Wojciech Wojtczak 2017-01-15 03:45:29 UTC 
I just installed (or dd'ed) FreeBSD-11.0-RELEASE-arm-armv6-RPI2.img.xz into SD card and booted into Rasberry Pi 2 board.

I attached USB 802.11n wireless card, which works fine and shows as below on dmesg(8) output.

urtwn0: <vendor 0x0bda product 0x8176, class 0/0, rev 2.00/2.00, addr 4> on usbus0
urtwn0: MAC/BB RTL8188CUS, RF 6052 1T1R
urtwn0: enabling 11n

... but this card is not listed in ifconfig(8) command as for example iwn0 cards are, why?

Regards,
vermaden

From https://www.freebsd.org/releases/11.0R/relnotes.html:
The wireless network stack has been modified to no longer show physical wireless devices by default. In order to view available wireless devices on the system, run sysctl net.wlan.devices. [r287197] (Sponsored by Netflix, Nginx, Inc.)

May I ask what is the purpose of that change?

Why not have ALL network interfaces in one place?

Hi,

There is some more information here:

Re-open if you think this is still a bug.

Thanks you.

I read that information as Release Notes aslo lead to it.

I understand WHAT has been done but I do not understand WHY.

Why having ALL network interfaces in one place is bad idea? (ifconfig)
