Stephen Hurd 35e4e998d8 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.

FreeBSD Source:

This is the top level of the FreeBSD source directory. This file was last revised on: FreeBSD

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.

The buildkernel and installkernel targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.

Note: If you want to build and install the kernel with the buildkernel and installkernel targets, you might need to build world before. More information is available in the handbook.

The kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
