[dpdk-dev] [PATCH v2 0/5] Support virtio multicast feature

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

 - V1 change:
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.

 -V2 change:
Rework the patch basing on new vhost library and new vhost application.

Changchun Ouyang (5):
  Add RX mode in VMDQ config and set the register PFVML2FLT for IXGBE
    PMD; this makes VMDQ accept broadcast and multicast packets.
  Set VM offload register according to VMDQ config for IGB PMD to
    support broadcast and multicast packets.
  To let US-vHOST accept and forward broadcast and multicast packets:
    Add promiscuous option into command line; set VMDQ RX mode into:
    ETH_VMDQ_ACCEPT_BROADCAST|ETH_VMDQ_ACCEPT_MULTICAST.
  Add new API in virtio for supporting promiscuous and allmulticast
    enable and disable.
  Specify rx_mode as 0 for 2 other samples: vmdq and vhost-xen.
