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:

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 

v3 changes:
* virnetdev.c
        * Fixed a syntax-check error in virNetDevGetRxFilter function
