e1000e: cleanup e1000_init_mac_params_82571()
Browse files Browse the repository at this point in the history 
Combine two switch statements into one, convert a nebulous pointer to one
that is a bit more in keeping with the rest of the driver code and cleanup
some coding style.  No change in functionality, just cosmetic changes.
