[9.312] Intel 82572EI e1000e Hardware Unit Hang

BarryG
Hi,

I have rebuilt one of my firewalls, using a Z87 motherboard and an Intel 82572EI PCIe NIC as eth1/WAN.

I'm now getting a LOT of e1000e "eth1: Detected Hardware Unit Hang" messages, and the firewall stops responding on ALL interfaces including LAN.

I notice the UTM says it is disabling TSO, but that doesn't seem to be enough.

If I run
ethtool -K eth1 tso off gso off  gro off
it gets MUCH better (maybe solved).

Where should I add this to init or udev?

lspci:
01:00.0 Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet Controller (Copper) (rev 06)

Thanks,
Barry

    Our escalation team,advise that there's no way to make 
    ethtool -K wlan# tso off reboot safe, we've had a few customers make scripts
    so the command is run again after a reboot, but there is no way to make that command reboot persistent.


    I've replied, asking why UDEV can't be used.
