During testing a new driver, I got a problem to test a monitor mode at
802.11 vap I'm using.
# uname -a

As seeing, it looks work but the problem is happend when I ran stumbler
(src/tools/tools/net80211/stumbler) program.
The error message is "ioctl(BIOCSDLT): Invalid argument" that it's
emitted to screen when I execute the following command:
# ./stumbler wlan0
Are there something I missed?
