Please can I ask this question again , as no-one replied. Having transmit rate limiting at 25Gbe/40Gbe for the Intel i40e driver (710 based cards) would be extremely useful for some applications. Does anyone have any thoughts on achieving this or is it on the roadmap for i40e ?

Is there a simplistic way of assigning just a single tx queue to a single queue set and setting its transmit bandwidth through set_queue_rate_limit ?Many thanksTerry
