We have recently come across what appears to be a driver/firmware problem with our Intel Ethernet Converged Network Adapter X710-DA2. Wanted to see if anyone had insight into whether it was a known bug and if any fixes/workarounds exist. Symptoms: On two FreeBSD 10.2-STABLE r292570 amd64 instances with these cards -- we experienced packet loss (incrementing packet error counts) at exactly the same time we observed /var/log/messages such as those below. Here are the details of our hardware/driver/firmware: Hardware: Intel Ethernet Card: X710DA2 Dual Port, SFP 10GbE, PCIe 3.0, x8 VendorID:8086, DvID:1572 FreeBSD Drivers we are running: # sysctl -a | grep dev.ixl.0.%desc dev.ixl.0.%desc: Intel(R) Ethernet Connection XL710 Driver, Version - 1.4.3 Intel Firmware we were running: # sysctl -a | grep dev.ixl.0.fw_version dev.ixl.0.fw_version: f4.40 a1.4 n04.53 e80001dc0 === /var/log/messages logs ==== Apr 2 00:45:40 server3 kernel: ixl0: Malicious Driver Detection event 0x02 on TX queue 15 pf number 0x00 Apr 2 00:45:40 server3 kernel: ixl0: MDD TX event is for this function 0x00000001ixl0: Malicious Driver Detection event 0x02 on TX queue 3 pf number 0x00 Apr 2 00:45:40 server3 kernel: ixl0: MDD TX event is for this function 0x00000001 Apr 2 00:45:41 server3 kernel: ixl0: Malicious Driver Detection event 0x02 on TX queue 12 pf number 0x00 Apr 2 00:45:41 server3 kernel: ixl0: MDD TX event is for this function 0x00000001 Apr 2 00:45:43 server3 kernel: ixl0: Malicious Driver Detection event 0x02 on TX queue 1 pf number 0x00 Apr 2 00:45:43 server3 kernel: ixl0: MDD TX event is for this function 0x00000001 Apr 2 01:12:03 server3 kernel: ixl0: Interface stopped DISTRIBUTING, possible flapping And on another box.

Anyone know if there was a reason for discrepancy? For Intel reps here, should we also upgrade firmware to the latest dev.ixl.0.fw_version: f5.0 a1.5 n05.02 e80002282 ? Thanks, Alvin Wong
