Kristof Provost 8f04209d37 pf: simplify pf_addrcpy() and pf_match_addr()
Use the v4/v6 union members rather than the uint32_t ones.
Export IN_ARE_MASKED_ADDR_EQUAL() in in_var.h and use it (and its IPv6
equivalent) for masked comparisons rather than hand-rolled code.

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.
