I recommend to change the semantics for unlimited number of segments
from 'value 0' to:

#define DMA_SEGMENTS_COUNT_UNLIMITED ((unsigned long)INT_MAX)

Sorry. It should be:
#define DMA_SEGMENTS_COUNT_UNLIMITED ((unsigned int)INT_MAX)

Using INT_MAX will allow using safe conversions between signed and
unsigned integers.

LONG_MAX seems cleaner regardless.
