| Split at position 123, then send packet 0 of 123 bytes (from splitting) out of order. The network filter will first receive packet 1, only then packet 0. |

| Split at position 123, then send packet 0 of 123 bytes (from splitting) out of order. The network filter will first receive packet 1, only then packet 0. This is done by setting the hop limit for the write to 1, and then restoring it. It will be sent with its original hop limit on retransmission. |

Allows to send TCP packets out of order
This is achieved by sending some packets with TTL=1, and then setting TTL back to normal.
Tested with the following command:
This splits the TCP request at position 123, at SNI record:
meduis in packet 0,za.iois in packet 1.The network filters will receive a packet containing
za.iofirst, then another packet withmedu.The receiver will then reassemble the packets in it's TCP stack.
Can be combined with
