[dpdk-dev] [PATCH 0/5] Support virtio multicast feature

[Ouyang Changchun <changchun.ouyang@intel.com>]

This patch series support multicast feature in virtio and vhost.
The vhost backend enables the promiscuous mode and config ETH_VMDQ_ACCEPT_BROADCAST
and ETH_VMDQ_ACCEPT_MULTICAST in VMDQ offload register to receive the multicast and broadcast packets.
The virtio frontend provides the functionality of enabling and disabling the multicast and
promiscuous mode.

Changchun Ouyang (2):
  Set VM offload register according to VMDQ config for IGB PMD to
    support broadcast and multicast packets.
  Add new API in virtio for supporting promiscuous and allmulticast
    enable and disable.

Ouyang Changchun (3):
  Add RX mode in VMDQ config and set the register PFVML2FLT for IXGBE
    PMD; this makes VMDQ accept broadcast and multicast packets.
  To let US-vHOST accept and forward broadcast and multicast packets:
    Add promiscurous option into command line; set VMDQ RX mode into:
    ETH_VMDQ_ACCEPT_BROADCAST|ETH_VMDQ_ACCEPT_MULTICAST.
  Specify rx_mode as 0 for 2 other samples: vmdq and vhost-xen.
