/sys/dev/if_ndis.c does not exist, however /sys/dev/if_ndis/if_ndis.c
does exist. I have commented out the line and executed:

make buildkernel
make installkernel

but it did not seem to fix the problem (I don't use modules -- I only
compile in what I need).

If I recall correctly, someone on IRC recommended I try disabling that.
Changing this setting had no effect -- the problem existed either way.
It is enabled now. No other sysctl options are in effect.
