Ok, assuming that my "Network traffic dumping for -netdev devices" patch
series is going to solve the dumping-for-netdev problem, how do we
tackle the remaining problems that we have to solve before we can
deprecate -net? Does anybody have a survey of the (onboard) NICs that
can only be configured with -net but not with -device? Could they
nowadays be changed to work with -device, too, or are there still major
obstacles to solve first?
