The goal is to enable MAC filtering at the kvm/qemu level for virtio-net packets. Promiscuous and allmulti mode are handled by adding bits to Mark's proposed status field. I also add a 16 entry MAC table for additional unicast and multicast addresses to filter. If this looks reasonable, I'll follow-up with VLAN filtering. As noted in the RFC thread adding the kvm/qemu backing, this does increase the size of the virtio-net device I/O port space, up to 1kB with PCI rounding if we add a 4k entry VLAN bitmap. A 64 device limit is still pretty high for a VM, but maybe we should think about adding MMIO space for virtio-pci. Thanks, Alex -- Alex Williamson HP Open Source & Linux Org.
