I am currently facing issues with getting the multicast IPv6 packets when using the i40evf pmd.
I do see there is a limitation mentioned in the release notes of DPDK that
16.27. I40e VF may not receive packets in the promiscuous mode
Promiscuous mode is not supported by the DPDK i40e VF driver when using the i40e Linux kernel driver as host driver.
The i40e VF does not receive packets when the destination MAC address is unknown.
Use a explicit destination MAC address that matches the VF.
Poll Mode Driver (PMD).
Do this mean that multicast promiscuous mode is also not supported ? I am currently facing issues with receiving packets multicast packets for IPv6 which is making IPv6 to fail with i40evf pmd.
I am currently using 17.11.2 DPDK with the Centos 7.5 and i40e 2.4.6 version on the host. I have the rte_eth_allmulticast_enable() also set for the port but still I see all multicast packets are not reaching the pmd.
Also if promiscuous mode has to be turned off then how should we add multicast address to the PF from the VF ?
