Date: Wed, 5 Oct 2011 03:20:21 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Emil Tantilov <emil.s.tantilov@...el.com>, netdev@...r.kernel.org, gospo@...hat.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next 07/10] ixgbe: send MFLCN to ethtool From: Emil Tantilov <emil.s.tantilov@...el.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).
