[dpdk-users] Requiring rte_eth_allmulticast_enable in 18.02.1

Hi all,

I managed to get 18.02.1 building and working for Mellanox MLX5 PMD.

I am using the Flow Director still, and previously with Mellanox 16.11_4.0 I had no problem receiving multicast packets.
With 18.02.1 I am forced to use rte_eth_allmulticast_enable to see multicast packets on the receive side.

Question: Is this expected, or should I be just adding the MAC address of the flow into the whitelist ?

I assume the old Flow Director code was doing this before, but somehow it looks like it's stopped doing this, perhaps in being switched over to use the new rte_flow underneath ?

Is rte_eth_allmulticast_enable, or adding the MAC addresses to whitelist required, or expected to be used with the new rte_flow ?
