So there is already a module option allowing you to change this, using
e.g kernel command line or kmod config files.  It's even writable,
taking effect on the next netdev open, so you can change it at runtime
without reloading the module.

What good does this new build-time setting do, except causing confusion
wrt driver defaults?

Note also that the smsc95xx and smsc75xx drivers are pretty similar.
Both have the same turbo_mode setting.  If you change the defaults, then
they should at least be kept in sync to cause as little confusion as
possible..
