Follow-ups

BFIN_MAC is not selected by default after kernel upgrade to 3.2.

We should select CONFIG_NET_BFIN and CONFIG_BFIN_MAC as default.

 

--- Vivi Li                                                  2012-01-17 02:49:58

Bob has fixed it in latest trunk.

Recheck later.

 

--- Mingquan Pan                                             2012-02-21 02:55:38

Yes, fixed. Close.
