[dpdk-stable] [PATCH v5] net/virtio: fix multicast and promisc mode enable failure

[Marvin Liu <yong.liu@intel.com>]

As doc mentioned, Rx/Mac/vlan filters are all supported by best effort.
These control commands should return pass. Promisc and all multicast
modes are always enabled in virio-user, initialize related values in
ethernet data.

Fixes: f9b9d1a55775 ("net/virtio-user: add multiple queues in device emulation")
