pbuf->len is the length of this pbuf. pbuf->tot_len is the sum of the lengths of this pbuf and all those chained together to form a packet using pbuf->next. Having pbuf->len=0 is a bit odd though. Is this for a received packet or one you are sending? Is there another pbuf linked by pbuf->next? If so, what is its length?
