Dear u-boot users,

i got u-boot 1.1.3 and linux 2.4.25 running on my custom MPC875-board.
But the ethernet-connection (FEC-Controller) seems to be abit slow. The
MII-transceiver chip autonegotiates a speed of 100MBit but when
downloading files via tftp/ftp in u-boot or linux the transfer seems to
happen in 10MBit mode.

Could this be caused by the low system clock (40MHz) ? What else ?

Best regards,
