Subject: [dpdk-dev] ixgbe: ierrors counter spuriously increasing in DPDK 2.1
Date: Wed, 21 Oct 2015 10:38:22 +0200	[thread overview]
Message-ID: <56274EFE.5040706@allegro-packets.com> (raw)

Hi,

with DPDK 2.1 we are seeing the ierrors counter increasing for 82599ES
ports without reason. Even directly after starting test-pmd the error
counter immediately is 1 without even a single packet being sent to the
device:

./testpmd -c 0xfe -n 4 -- --portmask 0x3 --interactive
...
testpmd> show port stats all

When packet forwarding is started the ports perform normally and
properly forward all packets but a huge number of ierrors is counted:

testpmd> start
...
testpmd> show port stats all

When running the exact same test with DPDK version 2.0 no ierrors are
reported.
Is anyone else seeing strange ierrors being reported for Intel Niantic
cards with DPDK 2.1?

Best regards,
Martin
