Kristof Provost 43877e6012 pf: avoid passing through dummynet multiple times
In some setups we end up with multiple states created for a single
packet, which in turn can mean we run the packet through dummynet
multiple times. That's not expected or intended. Mark each packet when
it goes through dummynet, and do not pass packet through dummynet if
they're marked as having already passed through.

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.
