u16_t pbuf::ref |
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.

u16_t pbuf::tot_len |
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)

u8_t pbuf::type |
