Hi All,
I am trying to support multicast packet over SRIOV using kernel
PF + DPDK VF(ixgbevf) drivers for ipv6. I am currently using 2.1 DPDK and found
that there was a patch in 16.04 for "ixgbe: support multicast promiscuous mode
on VF". So I have backported the patch to the 2.1 DPDK but still multicast
packets were not coming up to the DPDK app. Then I tried to enable the
rte_eth_dev_set_mc_addr_list and with the the packets were coming up properly.
Now I have some doubts :
1. Do we have to use both rte_eth_dev_set_mc_addr_list and
rte_eth_allmulticast_enable to get the multicast packets.
2. How do we get the mc_addr_list dynamically as I don't see we are using
the kni_net_set_rx_mode in rte_kni. Without this the DPDK app will not have any
idea to update the mc_addr_list in the PF.
3. Is there any other patches which I should be using to get this
functionality working.
I am using : DPDK -2.1
Host kernel - 4.4 ( ubuntu)
Guest kernel - 3.2 (Debian)
Drivers - ixgbe ( for both pf and vf).
Thanks in advance for the help and support.
