Subject: [PATCH v2 net-next 3/5] net: dsa: mv88e6xxx: Allow the SERDES interfaces to have statistics
Date: Thu, 1 Mar 2018 02:02:29 +0100 [thread overview]
Message-ID: <1519866151-13419-4-git-send-email-andrew@lunn.ch> (raw)
In-Reply-To: <1519866151-13419-1-git-send-email-andrew@lunn.ch>
When gettting the number of statistics, the strings and the actual
statistics, call the SERDES ops if implemented. This means the stats
code needs to return the number of strings/stats they have placed into
the data, so that the SERDES strings/stats can follow on.
