Bjoern A. Zeeb 5b7aa8225b LinuxKPI: skbuff: checksum offloading flags
Given the checksum offloading flags are mutually exclusive and are
not a bit mask, we can compress them into 2 bit for the four possible
values.  Change the define but leave the type at uint8_t for now with
a comment.  We can possible combine them with another sub-octet field
in the future.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
