+From c66a4e76c8554c84e64b9315314576ac403c6641 Mon Sep 17 00:00:00 2001

+Subject: [PATCH 645/660] net: sfp: add more extended compliance codes
+
+SFF-8024 is used to define various constants re-used in several SFF
+SFP-related specifications. Split these constants from the enum, and
+rename them to indicate that they're defined by SFF-8024.
+
+Add and use updated SFF-8024 extended compliance code definitions for
+10GBASE-T, 5GBASE-T and 2.5GBASE-T modules.
+
+Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
