My packets source:
FPGA with 4x lan (SFP TL-SM311LS)
My destination:
i7-4930K ( 6 cores with HT)
Intel 82599ES 2x2 lan (SFP TL-SM311LS)
Metod:
FPGA is programmed to send 512MB of data,
on PC create 4 threaads and use this metod, based on examples
//////////////
pfr = pfring_open('zc:ethX', 512, PF_RING_DNA_SYMMETRIC_RSS ||
PF_RING_PROMISC || PF_RING_STRIP_HW_TIMESTAMP)
pfring_loop(pfr , my_callback , 0);
//////////////
FPGA is programmed to send 512MB of data, I save it to file and compare
with source.
After send data I call pfring_stats and drop is always = 0 (for all
pfring)
But Received data is less , sometimes lost 144B , sometimes lost 432B
,few frames lost.
Identical errors on all network interfaces (strange?)
If pfring_stats return drop=0 but in my opinion few frames lost, where
find lost packets ?
