L4 ethernet driver and stack setup

[Leon Brits]

Hi all,

I've "extracted" the E1000 driver code from the TFTP server to get some
packet data directly into L4. I've noticed that if I load this task with
the loader then the TX part sends garbage. I then added (for fun) the
attribute (section "STACK") to the buffer from which the packet is send
and now it works.

Can anybody explain this to me! Send a link to some use full doc?
Thanks
Leon
