From 9a12a30627f76f839e81beba243371a60a5aa1db Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 5 Sep 2013 17:53:57 +0100 Subject: [PATCH] sfc: Minimal support for 40G link speed Accept and handle 40G link events. Accept ethtool link settings of speed == 40000 && duplex, and set the appropriate MCDI PHY capability. This does not include reporting of 40G media types, as those have not yet been assigned numbers in the MCDI protocol.
