From 0ae93b2cccbcc060899800a6bac7905a7d754448 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Mon, 2 Mar 2015 12:03:27 -0800 Subject: [PATCH] gianfar: Reduce logging noise seen due to phy polling if link is down Commit 6ce29b0e2a04 ("gianfar: Avoid unnecessary reg accesses in adjust_link()") eliminates unnecessary calls to adjust_link for phy devices which don't support interrupts and need polling. As part of that work, the 'new_state' local flag, which was used to reduce logging noise on the console, was eliminated. Unfortunately, that means that a 'Link is Down' log message will now be issued continuously if a link is configured as UP, the link state is down, and the associated phy requires polling. This occurs because priv->oldduplex is -1 in this case, which always differs from phydev->duplex. In addition, phydev->speed may also differ from priv->oldspeed. gfar_update_link_state() is therefore called each time a phy is polled, even if the link state did not change.
