Kristof Provost 83699dfd09 vtnet: Support jumbo frames without TSO/GSO
Currently in Virtio driver without TSO/GSO features enabled, the max scatter
gather segments for the TX path can be 4, which limits the support for 9K JUMBO
frames. 9K JUMBO frames results in more than 4 scatter gather segments and
virtio driver fails to send the frame down to host OS. With TSO/GSO feature
enabled max scatter gather segments can be 64, then 9K JUMBO frames are fine,
this is making virtio driver to support JUMBO frames only with TSO/GSO.

Increasing the VTNET_MIN_TX_SEGS which is the case for non TSO/GSO to 32 to
support upto 64K JUMBO frames to Host.

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 http://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 http://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.
