I found out that the "stripioctl: unknown request 0xc0286936"
message was because I had DEBUG defined in my kernel and the
if_strip device doesn't know how to deal with the SIOCGIFMEDIA
ioctl from ifconfig.

Which would be better, add a case for SIOCGIFMEDIA that returns
EINVAL, or remove the DEBUG printf in if_strip.c?
