Cover letter [PATCH v3 0/9] Introduce per-device completion queue pools
Quoted 8 lines · Sagi Grimberg

Additionally, on many setups each
RDMA port only runs a single ULP. I think that's another argument to let the ULP allocate CQ pool(s) instead of having one such pool per HCA.I think that most modern HCAs are exposing device-per-port and will probably continue to do so, But yes, mlx4 is dual-ported HCA.
I have patches in my queue for -next cycle which introduce similar functionality for mlx5 too - one mlx5_ib device with two ports.
Thanks
