I prefer to keep it together with route table image initialization.

For route table operations this will work. But there are Error
Management functions added in follow-up patches, which are different for
Tsi568. I prefer to keep them in different files to avoid hiding the
differences. Plus, it makes easier for end-user to remove from the build
drivers for switches that are not used in their system. I do not want to
add new configuration options for switch selection at this moment but we
may consider it later.
