NetBSD urtwn wifi driver

[Brook Milligan <brook%nmsu.edu@localhost>]

I have a Trendnet TEW-648UBM USB WiFi adapter, which seems to have a Realtek 8192C chip; the linux driver code is here:

	https://www.trendnet.com/support/support-detail.asp?prod=250_TEW-648UBM

Ifconfig reports the following:

urtwn0: flags=0x8803<UP,BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ssid ""
        powersave off
        address: 3c:8c:f8:f8:4c:6d
        media: IEEE802.11 autoselect
        status: no network

And

# ifconfig urtwn0 up
[ 1295.6492326] urtwn0: could not load firmware page 3

The following firmware is available in /libdata/firmware/if_urtwn:

-r--r--r--  1 root  wheel   2213 Oct 12  2016 Realtek-Firmware-License.txt
-r--r--r--  1 root  wheel  13904 Jul 20  2014 rtl8188eufw.bin

-r--r--r--  1 root  wheel  31818 Oct 12  2016 rtl8192eefw.bin

Is anyone working on NetBSD wifi drivers?

Is there missing firmware?  Is there something more that needs work in the driver?

Thanks for your help.

Cheers,
