From 76f6bf362addbda005740e01681d9fea83d7fbf6 Mon Sep 17 00:00:00 2001
From: Brad Smith <brad@cvs.openbsd.org>
Date: Thu, 7 Oct 2004 22:21:21 +0000
Subject: Add an Ethernet option bit for master mode (for 1000baseT, the link
 master provides the clock -- this is normally the switch, but if you are
 doing back-to-back NICs, you need to tell one side to be the master).
