Ankh Examples

[Ayad Mostafa]

hello l4 hackers,

i'm experimenting with ankh and so far failed to successfully ping morpork 
from my host machine. it seems that receive() blocks at wait_for_data() 
indefinitely. i can see irq activity on displayed on screen but wait_for_data() 
does not unblock.

i appreciate any help or ideas...

software version:
l4re revision r63 (2014-02-28)
gcc version 4.8.2
qemu version 1.7.0

qemu command:
qemu -cpu core2duo -m 128 -cdrom ./morpork.iso \
  -net nic,vlan=0,macaddr=00:e0:4c:c6:45:f4,model=rtl8139
  -net tap,vlan=0,ifname=tap0 -serial stdio

ping command:
arping -i tap0 00:E0:4C:C6:45:F4

output:
