Subject: [dpdk-dev] [PATCH] metrics: make number of metrics names configurable
Date: Thu,  2 Jul 2020 10:28:52 -0700
Message-ID: <20200702172852.6201-1-stephen@networkplumber.org> (raw)

The maximum number of metrics is hardcoded at 256.
This severely limits the usefulness of the library.
It should be configurable like other limits in DPDK.

Fixes: 349950ddb9c5 ("metrics: add information metrics library")
