[ECOS] Adding a 82544 driver Package to redboot

[G.Muruganandam]

Hello Andrew,

I have made some progress in integrating and testing the 82544 based driver 
on a IXP platform.

I have the following issue on the driver.

When I ping the host from IXP platform using the Giga bit ethernet 
interface, the tcpdump software
displays following information on the screen.


G:\Temp\WinDump.exe: listening on \Device\NPF_{BDE6BD48-A7D4-4F2C-9011-F3E
E9F}
18:16:36.863101 0:0:0:0:0:0 > 0:0:0:0:0:0 null I (s=0,r=0,C) len=42


This means that it (host)  is not getting the valid mac address from the 
target board.

I have verified the statistics counter for the reception and transmission 
of the packet in and out of the
interface.

I am seeing the non zero values on both counters. It means to me that it is 
there is no issue with basic
transmission or reception of packets.  Please correct me if I am wrong.


Also I tried to ping the target board from the host and executed the 
command arp -a at the
dos prompt, it displayed the following information.


DOS-PROMPT>arp -a

Interface: 192.168.200.165 on Interface 0x1000003
Internet Address      Physical Address      Type
192.168.200.198       00-00-00-00-00-00     invalid

It shows that host has received a invalid mac address for the ip address 
192.168.200.198.

I have verified the mac address read from EEPROM by including the printfs. 
it looks fine.

Valid EEPROM checksum
eth_set_mac_address
setting: lo FF48DEAC hi 80000006
Set MAC Address = AC DE 48 FF 06 00 (ok 1)
i82544_init: MAC Address = AC DE 48 FF 06 00


So please let me know how do I proceed further in terms of debugging this 
issue?

Thanks in advance.
