There are examples of similar naming schemes in other DSA drivers. For
the marvell mv88e6xxx driver, all generic functions use the mv88e6xxx_
prefix. For functions which are specific to a family of marvell
switches, we use a prefix for when the feature was introduced. So for
example we have mv88e6352_g1_reset(), where that method of resetting
the devices was introduced in the mv88e6352. This also gives us some
namespace space, so we can also have mv88e6185_g1_reset() which is
used for a different family.
So i personally don't have a problem using different prefixes within
one driver, if it helps with understanding and name space issues.

My experience with silicon vendors is that they like to change the
hardware in none backwards compatible ways. So i would actually avoid
generic names, it makes it harder to deal with different variants.
