Richard Scheffenegger 9028b6e0d9 Prevent premature shrinking of the scaled receive window
which can cause a TCP client to use invalid or stale TCP sequence numbers for ACK packets.

Packets with old sequence numbers are ignored and not used to update the send window size.
This might cause the TCP session to hang indefinitely under some circumstances.
