The function operates similarly to multisplit with a single split point, but it interleaves fake packets between real segments. Fake packets match the size of the segments being sent and are generated based on a pattern with an offset corresponding to the TCP sequence offset of the segment relative to the first one.

- `ipid_opts` and `rawsend_opts` are applied to both fakes and originals. `ipfrag_opts` are not used for either fakes or originals.
If the transmission is successful, a VERDICT_DROP is issued unless "nodrop" is specified.
The [blob](#передача-блобов) parameter allows replacing the current payload with an arbitrary [blob](#передача-блобов), enabling the transmission of any compatible payload using the same segmentation.
The [blob](#passing-blobs) parameter allows replacing the current payload with an arbitrary [blob](#passing-blobs), enabling the transmission of any compatible payload using the same segmentation.
