The existing code is setting the tot_len field of the first struct of a pbuf chain to a value double the correct value, and is failing to update the tot_len value of all pbufs in a chain when appending received data. This change fixes the above issues, which were causing a page fault in the pbuf_realloc() lwIP function during reception of an IPv6 packet.
