Support for the ne2000 (1)

[Till Straumann]

I really don't recall major problems with the ne2000_isa emulation.

Here's a script I use to start qemu. It contains a few comments
(don't remember the details but I do remember that you have to
change the interrupt number in your network interface configuration):

#!/bin/sh
#
# CAVEATS: qemu has irq hardwired to 9; must set this in RTEMS network 
configuration table (irno:9)
#          rtems application must not set ethernet address (would be 
unknown to qemu dhcp)
#
i386-softmmu/qemu -M isapc -s -L ../pc-bios -net nic,model=ne2k_isa -net 
user -cdrom tst.iso -tftp boot -redir tcp:4444::4444 -redir 
tcp:2159::2159 -redir tcp:24742::23 -hda img -boot d
