Of course :) ...actually I needed to tweak if.h
to make build.sh release work (because of missing
callout_t).

So yet another question; an easy way to fix the
problem is to introduce #ifdef _KERNEL in
struct ifnet like the below patch. Is it acceptable?
Or should I make if_watchdog_ch a pointer instead?

BTW, moving #include <sys/callout.h> out of #ifdef _KERNEL
doesn't work because struct callout of callout.h conflicts
with that of external/bsd/am-utils. (Fixing this conflict
is an option though...)

Thanks,
