Date: Tue, 27 Apr 2010 03:38:34 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: netdev@...r.kernel.org, gospo@...hat.com, Greg Rose <gregory.v.rose@...el.com>, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-2.6 PATCH] ixgbevf: Fix link speed display From: Greg Rose <gregory.v.rose@...el.com> The ixgbevf driver would always report 10Gig speeds even when the link speed is downshifted to 1Gig. This patch fixes that problem.
