This single patch is for people to get familiar with the optimization and is
for collecting feedbacks.
It isn't splitted because it is straightforward.
Haven't finished the cleanups.
The description and illustration of the idea is in a previous mail titled

Hello everyone.
Investigating IXGBE driver I found an mspdc counter (MAC Short Packet Discard).
And I am wondering why this counter is not used in the calculation of total RX
errors (ierrors field in rte_eth_stats structure). Is it already a part of

Hi Folks,
While doing some implementation with dpdk-1.7.0 on NIC 82599, I am facing

much faster, then the NIC starts to drop packets (of course, thi

I'm a newbie and testing DPDK KNI with 1G intel NIC.
According to my understanding of DPDK documents,
KNI should not raise interrupts when sending/receiving packets.
But when I transmit bunch of packets to my KNI ports,
