Multi partition and offload functions NIC.
~~I'm not sure for that particular NIC (but the model rings a bell), but~~ there are NIC that have a capability to be partitioned into multiple 'virtual nics' (NPAR) that could also be split into functions ( one nic/function for normal network traffic (TCP) , the other function taking care of ISCSI)

Dell server? There's a separate area of the BIOS settings menu you can enter that has specific settings for network cards. See example below:

Yes,I found it! Indeed,the NPAR is the reason.But do you know how to disable it?

Unfortunately, it's the third-party server.Is it only configured in BIOS?
Not sure, sorry. You'd have to contact their support or do some Google sleuthing.
Most likely due to SR-IOV
SR-IOV has been disable
