[OpenWrt-Devel] [PATCH v2 1/2] scripts/qemustart: no network by default and enable with -n

[Yousong Zhou]

This should make it easier to setup and possibly provide a "work out of
the box" experience for most test usage.  With typical wan&lan
networking setup being only two characters argument away.
