No problem. Will split the patch. Merging is on you though :) 
Regarding the MII support: This will include also a fix in the TSEC
driver to enable it to address all MII addresses on the bus, regardless
of the port (as someone asked here).

Regarding the thread number: As each UEC requires 8+ threads (4 for tx,
4 for rx), extending the number of UECs to 4 will exceed the number of
QE threads. Now, 4 threads per TX/RX is only required for the GBE UEC.
FE only requires one thread. So I'll change the driver in a way that it
will use 4+4 threads in case of GBE, and 1+1 in case of FE. I already
tested it here - and it worked fine. This way we won't need these CFG
options per UEC any more. Is this ok?

David.
