About this whole redundant_init thing... the Linux gianfar driver
doesn't do it, and it was added by this commit:

powerpc/mpc8548: Add workaround for erratum NMG_eTSEC129
Erratum NMG_eTSEC129 (eTSEC86 in MPC8548 document) applies to some early
verion silicons. This workaround detects if the eTSEC Rx logic is properly
initialized, and reinitialize the eTSEC Rx logic.

Internally I could find a single reference to the eTSEC 86 erratum
("eTSEC receivers may not be properly initialized"), dated 08/2007, and
it says it was fixed in MPC8548 silicon version 2.1.
On the other hand it consumes 90 lines of code (10%) of the tsec driver.
It would be nice if we could just remove it, I am not sure if anyone
would even notice.
Priyanka?
