Hi,
I am using Intel 82599 driver in my product. I see that out of 16 Rx
Queues, only *One Queue* is dropping all the packets. When I did a
test *to en-queue
packets only to the problematic Queue*, I found that the
-> Rx Missed Packet Count ( mpc ) is 0
-> Good Packet Received Count ( gprc ) in increased for received packets -
L2 filtering is pass.
What may be the reason for this behavior ?
For debug, I am also printing the "Queue Receive Descriptor Head" and
"Queue Receive Descriptor Tail" to get information about how many
descriptors are in-use. My question is, in further tests, if I find that No
Descriptor is in-use, however still packets are getting dropped -- Can I
infer Hardware Failure from it ?
Regards,
Kaushal
