[dpdk-dev] Regarding usage of vmxnet3 PMD with DPDK2.0

[Patel, Rashmin N]

That's correct. If you're using dpdk packaged vmxnet3 pmd, you should be able to bind it to igb_uio in Guest OS and start l2fwd/ l3fwd app in VM.

On the ESXi part, your vmxnet3 device must be connected to one of the vSwitches with Uplink port, so you don't need to configure anything else, I believe.
Just make sure the packets coming in the Uplink port carries your vmxnet3 device's mac-vlan and they'll hit your device and the VM, ultimately ending up in your dpdk thread polling on vmxnet3 device in your app.

Thanks,
Rashmin

I am migrating from using DPDK1.6r2 and the external vmxnet3 user map
driver to DPDK2.0.
I believe with DPDK2.0, the vmxnet3 PMD is builtin and I don’t need to
use the external driver.
I have been able to build the DPDK2.0 and I see that
CONFIG_RTE_LIBRTE_VMXNET3_PMD is set to y in the config.

Question is, what should be the steps that I follow on the ESXi node
in my virtual machine to detect the NIC with the above driver (I do
have vmxnet3 NIC there)
Should I load the uio and take over the NIC the usual way with igb_uio
and then run my application or are there any other steps to be
followed.
