From b30200616f97a81243e6d0c644d8ab06bf0b8115 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 28 Oct 2008 22:12:36 -0700 Subject: vlan: propogate ethtool speed values This enables more ethtool information. The speed and settings of the underlying device are propagated up. This makes services like SNMP that use ethtool to get speed setting, work when managing a vlan, without adding silly heurtistics into SNMP daemon. For the driver info, just use existing driver strings. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
