Gleb Smirnoff d2ef52ef3d tcp/hpts: make stacks responsible for clearing themselves out HPTS
There already is the tfb_tcp_timer_stop_all method that is supposed to stop
all time events associated with a given tcpcb by given stack.  Some time
ago it was doing actual callout_stop().  Today bbr/rack just mark their
internal state as inactive in their tfb_tcp_timer_stop_all methods, but
tcpcb stays in HPTS wheel and potentially called in from HPTS.  Change the
methods to also call tcp_hpts_remove().  Note: I'm not sure if internal
flag is still relevant once we are out of HPTS wheel.

Call the method when connection goes into TCP_CLOSED state, instead of
calling it later when tcpcb is freed.  Also call it when we switch between
stacks.

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.
