How do I use 10Gb NICs in VM

I have a new ESXi host that has 10Gb  network cards connected my iSCSI Equallogic SAN.  I created a VMkernel port and assigned both 10Gb nics to the vswitch.  Since I'm using the software iSCSI initiator within the VM for to mount SAN volumes, I assigned the VM one virtual NIC and connected it to my vswitch (iscsi switch).  When I log into the VM, the nic show up as 1Gb and not 10Gb.  Why is this?  Is there a setting that I'm missing?

What is the host? What are the 10GB Nics?

The host is a PowerEdge R910 and the NIC is Broadcom NetXteme II 57711 10GbE NIC.

Because the Network Interface Card within the Virtual Machine is a 1GB Network Interface Card. It does not represent the physical network interface card.

It's an E1000 — An emulated version of the Intel 82545EM Gigabit Ethernet NIC.

Have a read of the following link, Available Network Adapters in Virtual Machines

In ESX Configuration does it show 10GB on the vswitch->network adapters? If so you're ok.  I've seen vmxnet3 adapters show 10GB even though the underlying nic was only 1GB.

if you are using the Typical Wizard, you do not get the options to select the VMXNET3 network card, only when selecting the Custom Configuration

Correct OS support is required as well.
