John,
I have more detail for you. I've been able to identify a single
ethernet frame that (upon receipt) can cause this error. The ethernet
frame is attached (pod-t22.pcap).
Technically speaking this frame contains an SDP syntax error
(duplication) but that shouldn't matter to the e1000e/82574L
components (all other frame params are correct). When this pcap file
is replayed the 82574L interface drops and loses link.
I've hex-edited the frame to have correct SDP syntax. This edited
packet does not cause any errors and the NIC stays up. This is the
attached valid_sdp_edit.pcap
The logs are here:
http://pastebin.com/TpvrHwmG
It starts at system startup. At line 68 the pod-t22.pcap frame is
received. At this point (as you can see) the hardware is
irrecoverable until I physically power down the unit and power it back
up. Reboot and/or reloading the driver results in the errors starting
at line 110.
To be clear: a single receipt of pod-t22.pcap will kill the adapter
until power-off. Virtually all other traffic (including
valid_sdp_edit.pcap) passes perfectly well. Very strange.
Thanks!
