[dpdk-dev] vmxnet3 : testpmd failing with "eth_vmxnet3_dev_init(): Device is not configured for our purpose"

[Manoj Kumar Shetty <manojkumarshetty@gmail.com>]

Hi,

SOS. I'am trying to use DPDK in FC20 VM, with 2 VMXNET3 interface.

I followed the steps listed in "http://dpdk.org/doc/vmxnet3-usermap". for
enabling the VMXNET3 usermode driver

However, the "testpmd" fails/terminates with the below error
"EAL: PCI device 0000:03:00.0 on NUMA socket -1
EAL:   probe driver: 15ad:7b0 rte_vmxnet3_pmd
