[U-Boot] Gigabit support in UBOOT

Hi,

I'm using an ARM 922 based board.
It has gigabit ethernet support only. 
U-Boot Version used : U-Boot 2009.03

Problem faced: Unable to ping from my board.

 The terminal ends up with showing the Hardware address only. It's NOT
showing if the IP address is alive or not. On debugging I found that it
hangs after calling the function "NetSendUDPPacket(NetServerEther,
TftpServerIP, TftpServerPort, TftpOurPort, len);" defind in /src/net/tftp.c

If tftpcommand is issued it shows like this in the terminal.

TFTP from server 10.176.18.85; our IP address is 10.176.18.86; sending
through gateway 10.176.18.1
Filename 'uImage_er922'.

Load address: 0x11500000
Loading: *

Only the '*' is displayed. I was expecting 'E' or 'T' will be displayed. But
nothing is displayed in the terminal.

Also please note that I have connected my board to the PC directly and the
the 1000Mbps led lits up after negotiation.

Would like to know the reason for that.


Regards

Sreeju GR
