- 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.
