4 Subject: [PATCH] net: mscc: ocelot: change prototypes of switchdev port
5 attribute handlers
6
7 This is needed so that the Felix DSA front-end can call the Ocelot
8 implementations.
9
10 The implementation of the "mc_disabled" switchdev attribute has also
11 been simplified by using the read-modify-write macro instead of
12 open-coding that operation.
