[Qemu-devel] [PULL 10/13] net: Print output of "-net nic, model=help" to stdout instead of stderr

[Laurent Vivier <laurent@vivier.eu>]

From: Thomas Huth <thuth@redhat.com>

We are printing all other help output to stdout already (e.g. "-help",
"-cpu help" and "-machine help" output). So the "-net nic,model=help"
output should go to stdout instead of stderr, too. And while we're at
it, also print the NICs line by line, like we do it e.g. with the
"-cpu help" or "-M help" output, too.
