That may actually be unintentional.  The original code self-recursed, IIRC, so individual segments would then go through the non-gso-split path.  At some point we inlined it for efficiency.

The thing to try might be to copy the relevant code (both the search and the drop) into the gso-split path and see if anything breaks, and if the ack-dropping statistics tend to increase.
