From 55dffe79b34e2af98bd1315f1e00c2fc6a7a7078 Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Tue, 12 Jan 2010 10:11:39 +0000 Subject: [PATCH] tg3: Disable 5717 serdes and B0 support The B0 revision of the 5717 will not get enough testing by the time 2.6.33 ships. Since the kernel is already at RC3, serdes support will require too many patches to fix. For these reasons, this patch disables 5717 serdes support and will refuse to attach to all 5717 devices that are later than an A0 revision.
