What is the performance of the driver inside u-boot?
Get around up to 2 secs delay to "ping alive" and
Yes, the SMSC91C111 has an very long auto-negotation cycle...
downloading a 2.5MByte binary with tftp takes up to 7 secs.
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...
