Would you mind to do some clean ups?

I would suggest "debug_dish_network".

Please use static inline functions.

Please put a space after if, and between operators:
	delta = USEC_DELAY(lasttime, waketime);
	if (delta > 2500) {

Broken indentation. Please use one tab, not 8 spaces and certainly not 2 spaces.

Unnecessary cast.
