Minor patch for ipheth (iPhone ethernet interface)

Trivial suggested patch - as I keep having to reconstruct this from time to time. And my guess is that anyone who uses ipheth(4) will need to contract this regardless. 

Or is it better to propose a /etc/devd/ipheth.conf to be added when ipheth(4) is installed ?
