Hi there.

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 ?

Many thanks

Terry

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
