In contrast to Linux skbs, rtskbs consist of a single piece: the control
head + the buffer tail.

The buffer pointers (head, tail, end, ...) are initialised to point at
their own buffer. rtdev is an external reference to the unique
associated networking device. It's no buffer, it's the control structure
of that device!
