RTEMS networking (RTL 8139)

[Joe Samuel]

Thank you for your response. Setting the file
descriptors did fix the problem, but partially. Right
now I'm trying to fiqure out why I can't ping the
target system. I thought this is prebuilt to the
network demo program.

 I know I can't change the hardware address. I just
wanted to know that whether the address displayed by
the  netdemo program is my hw address. If so, it's
something diffrerent than that shown by ifconfig. What
does that mean? Is RTEMS identifying my NIC correctly?
with regards
Joe
