Here are some fixes for AF_RXRPC:
(1) Reenable IPv6 checksums on the UDP transport socket after the conversion to the UDP tunnel API disabled it.
(2) Fix listen() allowing preallocation to overrun the prealloc buffer.
(3) Prevent resending the request if we've seen the reply starting to arrive.
(4) Fix accidental sharing of ACK state between transmission and reception.
(5) Ignore ACKs in which ack.previousPacket regresses. This indicates the highest DATA number so far seen, so should not be seen to go backwards.
(6) Fix the determination of when to generate an IDLE-type ACK, simplifying it so that we generate one if we have more than two DATA packets that aren't hard-acked (consumed) or soft-acked (in the rx buffer, but could be discarded and re-requested).
