Help required with setting up TFTP communication between QEMU instance and host machine

[vivek kukreja]

Hi Chris,

Thank you for your prompt advice regarding tap interface.
I followed this mail chain and successfully run the ping01 example in rtems-libbsd:

https://lists.rtems.org/pipermail/users/2015-June/029063.html

Now I can ping and FTP into the QEMU instance from host machine!

Regards,
Vivek
