Am I doing something wrong with the VLAN?

I am having some major issue with a getting this to work.

  1. I have a chelsio t540 using port 0 is going to a DVSwitch Uplink while Port 1 using as an iSCSI Offload adapter. port 0 is DV uplink utagged. port 1 is VLAN11 10.30.30.231/24 I also have VLAN10 192.168.10.1/24 for iSCSI Multiplath.

There isn't anyway to assign a VLAN in ESXI for the iSCSI Offload adapter. So I have been using the switch (Dell PowerConnect) to put it in VLAN11. I have tried Access mode, General Mode, and Trunk Mode. the only way I have been able to get it to "work" was to use General Mode assign PVID=11 and VID=11U to the port where the T540 port 1 is connected to. however the outcome is not what it is expected.

I feel like I might be missing something in my configuration.

NOTE: If I setup a VMKernel Adapter for the T540 Port 1 using VMWare's software iSCSI, everything works as intended. Provided that I set up a VLAN Tag on the VSSwitch and setting General Mode VLAN11 Tagged. But I am trying to use the card as intended without the VMWare software iSCSI drivers.

Here are the ping results from the iSCSI Target:
