Some other NICs have indirection tables with a different/configurable size, and the current API does not help to manage it. For ConnectX-4 I have made a lot of hacks to avoid changing the DPDK API, "[dpdk-dev] [PATCH 0/3] Add RETA configuration to MLX5". http://dpdk.org/ml/archives/dev/2015-October/024681.html >>From a user point of view, to update the RETA table, the API expects the user to know the size of it to update or query. With your patchset, Intel have two indirection table sizes now, with Mellanox ConnectX-4, I fixed to the size of 512 entries because it is not fixed by default. How about discussing this in a separate thread? Regards, -- Nélio Laranjeiro 6WIND
