The last commit that touched this code path was:
commit 35e4e998d8187c1d4d413bdc13a79a6415a30a18
Author: Stephen Hurd <sh...@freebsd.org>
Date: Mon Nov 6 16:23:21 2017 +0000
Only chain non-LRO mbufs when LRO is not possible
Preserve packet order between tcp_lro_rx() and if_input() to avoid
creating extra corner cases. If no packets can be LROed, combine them
into one chain for submission via if_input(). If any packet can
potentially be LROed however, retain old behaviour and call if_input()
for each packet.
This should keep the 12% improvement for small packet forwarding intact,
but mostly avoids impacting the LRO case.
