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. examples/vhost/main.c | 27 ++++++++-- examples/vhost_xen/main.c | 1 + examples/vmdq/main.c | 1 + lib/librte_ether/rte_ethdev.h | 1 + lib/librte_pmd_e1000/igb_rxtx.c | 20 +++++++ lib/librte_pmd_ixgbe/ixgbe_rxtx.c | 16 ++++++ lib/librte_pmd_virtio/virtio_ethdev.c | 98 ++++++++++++++++++++++++++++++++++- 7 files changed, 159 insertions(+), 5 deletions(-) -- 1.8.4.2
