Subject: When set mtu 9600 by gfar_change_mtu, the maxfrm register is greater
 than 9600

Hi:

When set MTU to 9600 by gfar_change_mtu(), the maxfrm register will
be set to 9728 which is greater than 9600 in gianfar.c.

But the MPC8315 Reference manual says the value of maxfrm can not
greater than 9600.

Is it a defect, Do we need to fix it?
