Connecting from RHEL 5.4 via bnx2i using iscsi offload does not work

I can make iscsi connection trough real ethernet interfaces, but not trough ifaces. I would like to use offload properties of nic. I have not used hba before, but have used lot of time trying to figure this out. If anyone can help, I will be very happy. I am using RHEL 5.4. In console I get mesages: bnx2i: ISCSI not supported, dev=eth4
bnx2i: ISCSI not supported, dev=eth5

I already put this into other forum, but was adviced to send it here. I did not found any way to move it, sorry cross posting.

Thank you for any information,

Arto

I have following setup:

eth5      Link encap:Ethernet  HWaddr 00:10:18:5B:EB:9E, inet addr:10.10.13.6  Bcast:10.10.13.255  Mask:255.255.255.0, TCP-offload off

eth4      Link encap:Ethernet  HWaddr 00:10:18:5B:EB:9C, inet addr:10.10.13.5  Bcast:10.10.13.255  Mask:255.255.255.0, TCP-offload off
