I think so, too.

No, only the first time. After this a pbuf has been allocated and has been
assigned to q (which is the head of a pbuf chain).

What does happen if the byte stream doesn't has SLIP_END characters inside?
In my opinion the function will never terminate! Shouldn't the mtu be used
to force end of packet and a return in this case?
