+Subject: phy/marvell: disable 4-port phys
+Date: Wed, 20 Nov 2013 08:30:14 +0000
+Bug-Debian: https://bugs.debian.org/723177
+Forwarded: http://thread.gmane.org/gmane.linux.debian.devel.bugs.general/1107774/
+
+The Marvell PHY was originally disabled because it can cause networking
+failures on some systems. According to Lennert Buytenhek this is because some
+of the variants added did not share the same register layout. Since the known
+cases are all 4-ports disable those variants (indicated by a 4 in the
+penultimate position of the model name) until they can be audited for
+correctness.
+
+[bwh: Also #if-out the init functions for these PHYs to avoid
+ compiler warnings]
