i had problems getting the plb_temac driver to work at speeds higher
than 10 mbps until i modified the adapter.c
file to have the correct PHY address for my setup (i am using the
avnet V4FX12 mini-module board and the correct value was 4).
the phy address is usually determined by pullup/pulldowns on certain
pins on the gig phy chip.
this was under 2.4, but i looked at the adapter.c for the 2.6
xilinx_temac driver and it appears to just set this value to 0
look at line 2905 of adapter.c:
/* Assume the PHY to be at address 0x00 */
lp->gmii_addr = 0;
you should change that to reflect the address of your hardware setup.
hope this helps
