From fff6df7bf58e8907c710832738a26d8d67c8256c Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Wed, 19 Dec 2018 11:59:50 +0000 Subject: [PATCH] telemetry: fix using ports of different types Different NIC ports can have different numbers of xstats on them, which means that we can't just use the xstats list from the first port registered in the telemetry library. Instead, we need to check the type of each port - by checking its ops structure pointer - and register each port type once with the metrics lib.
