When a DL packet is deemed as invalid (exceeds expected + receive window), the packet should be placed onto a buffer. If the following N packets received are in sequence (each being placed onto the buffer in turn) then they should be sent to Layer 2 & the expected sequence number be updated to be the next in this sequence. If however one of the following packets received before N is reached is not in sequence, all packets on the buffer should be discarded.
