Hi,

I am also keen to know the answer to the question posted by Srini.
The real question is -- is dpdk1.6.0r1 self-sufficient so that I don't need any extensions etc., or do I still need something from outside like the usermap kernel driver etc.

Secondly, if I turn on all the debug options for the vmxnet3 pmd in the config file, 1.6.0r1 compilation runs into a problem and reports a function which is defined but not used.

I am trying to bring up DPDK inside Fedora18 Guest on ESXi -- when I used DPDK1.6.0r1 (without debug options turned on for vmxnet3 pmd) the igb_uio could take over the vmxnet3 NIC but I encountered a core dump in the dev init function for the vmxnet3 driver -- anybody encountered a similar issue ?

Regards
-Prashant

I want to try dpdk with vmxnet3 in Vmware Esxi 5.1. I see that the latest dpdk 1.6.0r1 includes a vmxnet3 pmd. The vmxnet3-usermap-1.1.tar.gz as well includes a vmxnet3 pmd driver.

I'm confused as to which vmxnet3 pmd driver to use along with which
vmxnet3 kernel driver (vmxnet3 native kernel driver or vmxnet3-usermap kernel driver). I also want to try RSS with vmxnet3 and dpdk. As per Intel DPDK Programmer's Guide (January 2014) RSS is supported with
vmxnet3 since dpdk version 1.6.0.

Thanks,
Srini
