What will it take to get the Ethernet port working?

[waldo]

I have one working board and one broken one ; I've been playing around with the rx tx values.
Results are attached ...  The Pine stopped rebooting at 1 1, didn't have a monitor attached so don't know why.

The wget and iperf are from a local apache server capable of delivering over 70 MByte/s http no problem

 The good results for tx1rx1 had me hopefull but those were clearly just a fluke. Tried them again afterwards ... no luck.

I'm beginning to think there might be no software quickfix for this issue.
Anyone willing to prove me wrong ... be my guest; my script is attached too, haven't gone above 1 x 3 yet.
(Just add a line to /etc/rc.local containing the scripts location)

Godspeed

Code:

#!/bin/bash

sleep 1m

RX=$(cat /sys/module/sunxi_gmac/parameters/rx_delay)
TX=$(cat /sys/module/sunxi_gmac/parameters/tx_delay)
tx)

if [ $RX -eq 31 ] && [  $TX -eq 7 ]; then
exit 1

if [  $TX -eq 7 ]; then
