You're missing a dependency in your kernel config. Best way to  
resolve this with the most learning experience is to take your  
drivers included in your kernel and go "man {driver name}". The man  
page lists all the dependencies for the required driver.

As a hint though, I bet the driver you're missing is net related,  
most likely dealing with bpf, ether, or options INET.

Make sure to run make clean when changing options if you have  
NO_CLEAN set to yes in /etc/make.conf.
