[dpdk-dev] Vmxnet3-pmd not receiving ANY packets

Hi,

I'm having a problem with vmxnet-pmd.  When I bind vmxnet3 vNIC to
vmxnet3-pmd, I cannot receive ANY packets from vmxnet-pmd.

I'm running dpdk-1.6.0r2 inside ESXi 5.5 VM.   The VM has kernel
3.11.0-12-generic.

One thing I notice is that ESXi host does not pass "pdpe1gb" CPU flag to
guest VMs,  so I have to use 2MB hugepages inside the VM.  Hope that's not
an issue.

Can anyone give me help how to troubleshoot this issue?   Will be much
appreciated.


Below is the output of igb_uio_bind.py and l2fwd:

There are two physical ports used by DPDK:

"0000:0b:00.0" (Port 0) is bound to ixgbe pmd.  I can receive packets from
this port.

"0000:13:00.0" (Port 1) is bound to vmxnet3_pmd.  I cannot receive ANY
packets from this port.
