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.

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.
