Dear Sir,

I have still a problem for using TFTP test code.

As I check in rtems_tftp_open_works() function, I guess that BOOTP should
be enabled for running TFTP.
At this time, if_address, ip_netmask and hardware_address of struct
rtems_bsdnet_ifconfig are NULL.

I don't know TFTP operation is related with BOOTP.

Please advise me.

Best Regards,
