Yes, the SMSC91C111 has an very long auto-negotation cycle...

Wow, about 3 MBit -- that's good for the Chip. The SMSC91C111 self isn't 
fast enough. It has an non performant chip design (there are only 2x2KByte 
for FIFO). My latest tests with an PXA255 a/o NIOS + SMSC91C111 @ 32 bit bus 
results the same...
