In the intel BIOS, (when your press <ctrl-D>, you can see intel PCI-E NIC's iSCSI boot setup menu, where you can select which NIC as your primary, which as your secondary. And set up their configuration separately.
Following is the iscsibcg.exe /ShowiBF

Good day Sonny,
In regards to your request to have two paths to an iSCSI target:
I'm going to guess that you are using Windows. If that's true, I would
be interested in seeing the output from:
iscsibcg.exe /ShowiBF
for your scenario involving the Intel NICs which you say support this
scenario.
