Hi,
Patch below makes qemu -net nic -net tap work when you don't specify an
ifname, ie stops it always printing garbage like:
$ ../qemu -hda test.img -net nic -net tap
warning: could not open
NL@
: no virtual network emulation
Could not initialize device 'tap'
I sent this to the maintainer a few weeks ago but no response.
It doesn't seem to be fixed (at least if it is, not in the same way) in
qemu cvs, so I'm going to file a bug report with them too.
