Subject: [dpdk-dev] [PATCH v3 2/2] telemetry: add extra log message on socket bind failure
Date: Wed,  7 Jul 2021 13:52:55 +0100	[thread overview]
Message-ID: <20210707125255.664793-2-bruce.richardson@intel.com> (raw)
In-Reply-To: <20210707125255.664793-1-bruce.richardson@intel.com>

If the library fails to create the needed socket, add an additional
check to report if the error is due to a missing DPDK runtime dir.
