length of this buffer

next pbuf in singly linked pbuf chain

pointer to the actual data in the buffer

the reference count always equals the number of pointers that refer to this pbuf.

This can be pointers from an application, the stack itself, or pbuf->next pointers from a chain.

total length of this buffer and all next buffers in chain belonging to the same packet.

For non-queue packet chains this is the invariant: p->tot_len == p->len + (p->next? p->next->tot_len: 0)

pbuf_type as u8_t instead of enum to save space
