From d4604348ca447b103c1f56f6ebeea53c3cca49eb Mon Sep 17 00:00:00 2001 From: Mark McLoughlin Date: Tue, 6 Oct 2009 12:17:16 +0100 Subject: [PATCH] Final net cleanup after conversion to QemuOpts Now that net_client_init() has no users, kill it off and rename net_client_init_from_opts(). There is no further need for the old code in net_client_parse() either. We use qemu_opts_parse() 'firstname' facitity for that. Instead, move the special handling of the 'vmchannel' type there. Simplify the vl.c code into merely call net_client_parse() for each -net command line option and then calling net_init_clients() later to iterate over the options and create the clients.
