Message-ID: <1333393300-5102-1-git-send-email-mcarlson@broadcom.com> Date: Mon, 2 Apr 2012 12:01:40 -0700 From: "Matt Carlson" <mcarlson@...adcom.com> To: davem@...emloft.net cc: netdev@...r.kernel.org, mcarlson@...adcom.com, mchan@...adcom.com Subject: [PATCH] tg3: Fix 5717 serdes powerdown problem If port 0 of a 5717 serdes device powers down, it hides the phy from port 1. This patch works around the problem by keeping port 0's phy powered up.
