Subject: [PATCH] net/i40e: reduce the ITR interval of multi-driver mode
This patch change the interrupt interval from 8160us to 32us to improve the
performance of multi-driver mode.
Signed-off-by: Qiming Yang <qiming.y...@intel.com>
Acked-by: Qi Zhang <qi.z.zh...@intel.com>
Applied to dpdk-next-net-intel.
The patch also looks good for backporting, so added Cc stable tag.
Hi. This looks like it is not fixing anything and it is changing a
behaviour, so I won't take for 21.11.4.
thanks,
Kevin.
Thanks
Qi
