Tsirkin" The "-net dump" option only works with the "-net" option. So far, it is not possible to dump network traffic with the "-netdev" option yet. This patch series now fixes this ugliness by enabling dumping for the netdev devices via the new netfilter infrastructure. It can be used like this for example: qemu-system-ppc64 -nographic -vga none -device virtio-net,netdev=mynet \ -netdev user,id=mynet,tftp=/tmp/tftp,bootfile=zImage -boot n \ -netfilter dump,id=f0,netdev=mynet,file=/tmp/filterdump.dat This series is based on v8 of Yang Hongyang's netfilter patches (i.e. these have to be applied before the dumping patches can be used). Since these netfilter patches are not upstream yet and still might change the API in future versions, I'm sending my patches as "RFC" (but since the integration with the current netfilter patches was pretty easy already, they should be ready as normal patches very soon after the netfilter patches have been finalized).
