Subject: [net-next 07/11] ixgbe: send MFLCN to ethtool
Date: Thu, 29 Sep 2011 22:24:47 -0700 [thread overview]
Message-ID: <1317360291-5576-8-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1317360291-5576-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Emil Tantilov <emil.s.tantilov@intel.com>
MFLCN register is used to set Rx flow control on parts newer than 82598.
This patch sends the value of MFLCN to ethtool, so it can be used in a
register dump (ethtool -d).
