Subject: [PATCH net-next v3 2/3] net: ethernet: bgmac: unify code of the same family
BCM471X and BCM535X are of the same family (from what I can derive from
internal documents). Group them into the case statement together, which
results in more code reuse.
Also, use existing helper variables to make the code a little more
readable too.
