Hi Vlad, 
   as you say,It isn't just the vlan table, although it is the mostly obvious one (particularly in rhel7 qemu-kvm package).
   On the surface´╝îI can't reproduce this issue on qemu-kvm-rhev version, so can you tell me how I can verify this bug with qemu-kvm-rhev version?

Thanks
Wei

Reproduce this bug with below version:
qemu-kvm-rhev-2.3.0-23.el7.x86_64
3.10.0-447.el7.x86_64

Test steps:
1.launch a guest with mq
-netdev tap,id=tap0,queues=4,vhost=on  -device virtio-net-pci,netdev=tap0,id=net0,mac=52:54:01:ee:0e:28,bus=pci.0,addr=0x10,mq=on,vectors=10
2.check the rx-filter information without a network name argument.
{"execute":"qmp_capabilities"}
{"return": {}}
{ "execute": "query-rx-filter"}
{"return": [{"promiscuous": true, "name": "net0", "main-mac": "52:54:01:ee:0e:28", "unicast": "normal", "vlan": "all", "vlan-table": [4095, 4094, 4093, 4092, 4091, 4090, 4089, 4088, 4087, 4086, 4085......

Vlan table display repeat four times,so reproduced this bug.
----------------------------------------------------------------------
Verify this bug with below version:
qemu-kvm-rhev-2.6.0-26.el7.x86_64
3.10.0-447.el7.x86_64

the same test steps:
{ "execute": "query-rx-filter"}
{"return": [{"promiscuous": true, "name": "net0", "main-mac": "52:54:01:ee:0e:28", "unicast": "normal", "vlan": "all", "vlan-table": [4095, 4094, 4093, 4092, 4091, 4090, 4089, 4088, 4087......0
Vlan table display only one time.

no repeat display vlan table, So this bug fix well.
