From 78cd6f7bf6b196a96388a37e730706cf0c497fda Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 21 Feb 2018 11:18:36 +0100 Subject: net: Add a new convenience option "--nic" to configure default/on-board NICs The legacy "-net" option can be quite confusing for the users since most people do not expect to get a "vlan" hub between their emulated guest hardware and the host backend. But so far, we are also not able to get rid of "-net" completely, since it is the only way to configure on-board NICs that can not be instantiated via "-device" yet. It's also a little bit shorter to type "-net nic -net tap" instead of "-device xyz,netdev=n1 -netdev tap,id=n1". So what we need is a new convenience option that is shorter to type than the full -device + -netdev stuff, and which can be used to configure the on-board NICs that can not be handled via -device yet. Thus this patch now provides such a new option "--nic": It adds an entry in the nd_table to configure a on-board / default NIC, creates a host backend and connects the two directly, without a confusing "vlan" hub inbetween.
