This patch series makes it later so that mv3310_config_init() correctly
initializes even 2210 (this is done in patch 07/18). The function then
calls chip->get_mactype() and chip->init_interface() methods, which are
different for 3310 than for 2110.

I am thinking about whether all the functions which are same for all
the chips should be renamed from
  mv3310_*
to
  mv10g_*

This would rename
  mv3310_config_init
to
  mv10g_config_init
which would be more correct.

What do you think?
