With the latest release, support for vdev ethernet devices like pcap,
tun and tap are been added. Hence collecting statistics using proc-info
is possible now.

This support is enabled when device shared between primary & secondary. The
capability to share virtual devices added that is correct, but still user may
prefer to use virtual device as process only.
Not sure if it worth mentioning stats retrieving supported when virtual device
is shared between processes, what do you think?

The document update is for procinfo tool, which is secondary process to collect stats for NIC interfaces under primary process.
Earlier documentation states since DPDK multi process has limitation in sharing virtual interface stats. The correction updates the same.

but still user may prefer

Proc info info tool purpose is collect stats from primary. Hence whether the primary process uses physical or virtual it is user discretion. But collecting stats is possible for any NIC device via proc info tool.

With the above reasoning, I believe proc info tool is state it can collect stats from both virtual and physical NIC is correct.

Sorry, I removed it from the pull to mainline.
I think it is wrong listing vdevs as supported in "Limitations".
Please send a patch for simply removing the line.

Hi Thomas,

With DPDK 18.11-rc4 I still see issues at times, Hence more test is required before I can send the change in request.

Thanks
