[9.171][BUG] Intel NIC hang

Hi,

I was doing some local LAN network load testing with Iperf on my new hardware, and Iperf suddenly got a Network Error.

I looked in the UTM's kernel log and found a corresponding error there for eth1.

eth1 is an Intel PCIe card, with Intel 82572EI chip, in a PCIe x16 slot.

Motherboard is a Gigabyte GA-Z87N-WiFi with Intel Z87 chip.

Iperf was running on separate machines, not on the firewall.

IPS and ATP were running, all other features were disabled.

Hi,

Still failing on 9.191-2, PCIe Intel 82572EI NIC.

(and the onboard NIC is i217-V, which is not failing)

Hi,

Still failing on 9.191-2, PCIe Intel 82572EI NIC.

(and the onboard NIC is i217-V, which is not failing)
