From 5b9c3cdd55ba57a25ae586373aaff723d8150085 Mon Sep 17 00:00:00 2001 From: Don Skidmore Date: Mon, 26 Jan 2009 20:57:17 -0800 Subject: [PATCH] ixgbe: fix slow load times on 82598 nics Load times for NICs that use i2c to communicate with the phy were taking ~4.5 sec per port. This fix first checks to see if the link is already up before calling get_link_capabilities, since if it is we don't need query the phy for link state.
