From 5ff1547b756a820bc7b695fe393b25d82467d1fe Mon Sep 17 00:00:00 2001 From: Scott Feldman Date: Wed, 10 Jun 2015 18:21:20 -0700 Subject: [PATCH] rocker: bring link up/down on PHY enable/disable When the OS driver enables/disables the port, go ahead and set the port's link status to up/down in response to the change. This more closely emulates real hardware when the PHY for the port is brought up/down and the PHY negotiates carrier (link status) with link partner. In the case of qemu, the virtual rocker device can't really do link negotiation with the link partner as that requires signally over a physical medium (the wire), so just pretend the negotiation was successful and bring the link up when the port is enabled.
