Re: [libvirt] [PATCH v3 0/2] Sync macvtap device modes when guest rxfilter changes

From: Tony Krowiak <akrowiak(a)linux.vnet.ibm.com&gt; This patch set provides the code to synchonize some macvtap device modes when the values are changed on the guest's network device. The following modes will by synchronized: * PROMISC * MULTICAST * ALLMULTI I noticed something while testing this patch set that did not occur prior to installing more recent kernel and Qemu distributions. It seems that the VLAN table always has an entry for VLAN ID 0 when the rxfilter is queried during processing of the NIC_RX_FILTER_CHANGED event. That means that the PROMISC flag for macvtap0 will be set. I don't know if this will cause problems, but I thought I'd make note of it in case anybody wants to comment on that. v2 changes: * virnetdev.c * Changed names of virNetDevIs... functions to virNetDevGet... * Consolidated code for getting/setting of device option flags * qemu_driver.c * Replaced "default" case in syncNicRxFilterMultiMode function with VIR_NETDEV_RX_FILTER_MODE_NONE v3 changes: * virnetdev.c * Fixed a syntax-check error in virNetDevGetRxFilter function Tony Krowiak (2): util: Functions for getting/setting device options qemu: change macvtap device options in response to NIC_RX_FILTER_CHANGED
