I am also seeing this on our Lenovo SR650 7x06 servers. We too are using 10GbE
XL710 cards:
Intel(R) Ethernet Controller X710 for 10GbE SFP+

This is easily able to be reproduced when hooking 10GbE VMWare ESXi hosts up to
these storage servers via iSCSI. We could trigger it by performing a vMotion
move from one datastore to another.
I do not have a test server that I can test any patches on as 3 of these exist
in production running 11.1-RELEASE and cannot afford to have them off-line or
deviate away from the standard supported freebsd-update mechanism.
I hope something can be worked out pretty soon and rolled into update as this
issue for us can't wait for 11.2 or 12.
I will be trying out -tso, but was trying to avoid that for performance
reasons.
Thanks!
