From 66846048f55c6c05a4c46c2daabb773173f8f28d Mon Sep 17 00:00:00 2001 From: Rick Jones Date: Mon, 14 Nov 2011 14:17:08 +0000 Subject: enable virtio_net to return bus_info in ethtool -i consistent with emulated NICs Add a new .bus_name to virtio_config_ops then modify virtio_net to call through to it in an ethtool .get_drvinfo routine to report bus_info in ethtool -i output which is consistent with other emulated NICs and the output of lspci.
