Subject: [PATCH v6 4/8] latencystats: fix log messages
Date: Wed, 29 May 2024 15:54:41 -0700	[thread overview]
Message-ID: <20240529225732.442539-5-stephen@networkplumber.org> (raw)
In-Reply-To: <20240529225732.442539-1-stephen@networkplumber.org>

All messages that because of an error should be at log level
NOTICE or above. Do not break log messages across lines.
Reword message for the case where getting info about a port
fails and it is skipped.
