Detailed Description

Single item of a linked list of descriptors.

Although descriptor list lengths are very likely to be constant throughout the runtime of the firmware, lists are allocated at runtime. To be able to allocate variable length lists, items are allocated one at a time. next is used to refer to the next item in the list. If this is the last item in the list, next will be equal to NULL.
