maybe include i40e maintainer in the email addresses then he may see the question. he email is in the maintainers file.

> Hi All,Is anyone working on some way of implementing transmit rate limit control in the i40e driver ?I realise the X**710 Intel chip implements queue sets, where the tx queues can be assigned to a queue set and the set given an overall transmit rate - so its not as simple as the ixgbe PMD driver.  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
