Hi, 

I am trying to receive packets as fast as possible with DPDK PMD. 
Sometimes packets arrive within a few microseconds , which is fine, 
sometimes packets arrive only after approx. 8 milliseconds. This seems to 
be due to interrupt throttling configured in the VF driver. Does anyone 
know a way to configure the interrupt throttling or how to turn it off. 

My setup: Intel XL710 NIC, i40e pmd driver, DPDK uses VF, PF is mapped to 
Linux kernel. DPDK 17.11


Thanks
Heiko
