Network Issue with Mini2440

Hello,

I'm trying to port the last release of barebox to my sbc2440-III board with
the base config. of a mini2440 but unfortunately I'm facing a network issue
when trying to boot from nfs or to load files with tftp.

After checking all the parameters (pll, ram init etc.) I figured out that
the chip select and interrupt pinout were not good and I changed them to
fit with my board schematic.
So I have a well boot on barebox everything seems to work as you can see
here :

running /env/bin/init...



But,  when I try to ping or boot from nfs/tftp, the phy isn't receiving any
packet from host :

Hit any key to stop autoboot:  0

warning: No MAC address set. Using random address F6:48:4B:C2:51:44

phy0: Link is up - 100/Full

I'm sure the host is well configured because I usually have to work with
other boards using nfs and tftp.

Here is more complete log of the packets transaction I hope it could help :

Any help is welcome for sure.
