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 ######################## NIC statistics for port 0 ######################## RX-packets: 0 RX-missed: 0 RX-bytes: 0 RX-badcrc: 0 RX-badlen: 0 RX-errors: 1 RX-nombuf: 0 TX-packets: 0 TX-errors: 0 TX-bytes: 0 ############################################################################ ######################## NIC statistics for port 1 ######################## RX-packets: 0 RX-missed: 0 RX-bytes: 0 RX-badcrc: 0 RX-badlen: 0 RX-errors: 1 RX-nombuf: 0 TX-packets: 0 TX-errors: 0 TX-bytes: 0 ############################################################################ 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 ######################## NIC statistics for port 0 ######################## RX-packets: 9011857 RX-missed: 0 RX-bytes: 5020932992 RX-badcrc: 0 RX-badlen: 0 RX-errors: 9011753 RX-nombuf: 0 TX-packets: 9026250 TX-errors: 0 TX-bytes: 2922375542 ############################################################################ ######################## NIC statistics for port 1 ######################## RX-packets: 9026250 RX-missed: 0 RX-bytes: 2922375542 RX-badcrc: 0 RX-badlen: 0 RX-errors: 9026138 RX-nombuf: 0 TX-packets: 9011857 TX-errors: 0 TX-bytes: 5020932992 ############################################################################ 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
