Hi:
I am developing a dpdk program using a Meallanox ConnectX-5 100G.
when i start the progra, it reports an error:
mlx5_net: Port 0 Rx queue 0 CQ creation failure
mlx5_net: Port 0 Rx queue allocation failed: Cannot allocate memory


I tried to increment the number of hugepages, but with no success.
Has anyone ever had a same probolem?
Thanks for your help!
