ISCSI network traffic - preferred interface metric - 10gbe traffic out through 1gbe incorrect chksum

[apnetworks]

Just troubleshooting some slow ISCSI read numbers and doing a TCPDUMP from an SSH session to the TrueNas box. I see ISCSI traffic on 3260 going out to the ESXI host on the 1g interface with incorrect chksum and coming back from the ESXi host on the 10g interface with correct chksum.

I'm wondering if there's a way to make sure the slow read speeds aren't due to iscsi traffic being routed through the 1gbe adapter. Anyone know a good way to adjust this metric?
