Hi Sharon,
I have the same problem.
1. FreeBSD 11.1-RELEASE
2. ixl0: <Intel(R) Ethernet Connection XL710/X722 Driver, Version - 1.7.12-k>
ixl0: fw 5.0.40043 api 1.5 nvm 5.04 etid 80002505 oem 0.0.0
3. this is iscsi target server. If traffic with high load is flowing on the server, error log will occur frequently.
ixl0: WARNING: queue 2 appears to be hung!
ixl0: WARNING: Resetting!
ixl0: Malicious Driver Detection event 2 on TX queue 6, pf number 0
ixl0: MDD TX event is for this function!
It does not solve even driver version 1.7
Regards,
Takunii
