Randall Stewart ca1a7e1021 tcp: TCP_LRO getting bad checksums and sending it in to TCP incorrectly.
In reviewing tcp_lro.c we have a possibility that some drives may send a mbuf into
LRO without making sure that the checksum passes. Some drivers actually are
aware of this and do not call lro when the csum failed, others do not do this and
thus could end up sending data up that we think has a checksum passing when
it does not.

This change will fix that situation by properly verifying that the mbuf
has the correct markings (CSUM VALID bits as well as csum in mbuf header
is set to 0xffff).

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
