           Summary: [urtwn] discard frame, too short - flakey performance
                    - sometimes not even dhclient succeeds
           Product: Base System

As reported on #freebsd-wifi and also forums, urtwn seems flakier
than under 10.3R on both rasp pi, and normal x86 hardware:

Oct 20 13:13:28 akai kernel: wlan0: [74:da:38:7e:e6:e0] discard frame, too
short (1): len 10
Oct 20 
13:13:28 akai kernel: wlan0: [74:da:38:7e:e6:e0] discard BAR frame, no BA
stream, tid 0
Oct 20 13:13:28 akai kernel: wlan0: [74:da:38:7e:e6:e0] discard frame, too
short (1): len 10

Occurs frequently in the logs and while association is quick, the system is
unable to pick up a dhcp address, even when one can see it being offered by
the the upstream AP. In my case, APs are Ubiquiti UAC PRO in a variety of
places, all within good range.

I have also enabled in /boot/loader.conf
# edimax wifi
# using 11n =1 or 11n=0 seems not to make any significant impact.

Resulting in:

wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
