Mark Johnston 3aff4ccdd7 netinet: Remove IP(V6)_BINDMULTI
This option was added in commit 0a100a6f1e but was never completed.
In particular, there is no logic to map flowids to different listening
sockets, so it accomplishes basically the same thing as SO_REUSEPORT.
Meanwhile, we've since added SO_REUSEPORT_LB, which at least tries to
balance among listening sockets using a hash of the 4-tuple and some
optional NUMA policy.

The option was never documented or completed, and an exp-run revealed
nothing using it in the ports tree.  Moreover, it complicates the
already very complicated in_pcbbind_setup(), and the checking in
in_pcbbind_check_bindmulti() is insufficient.  So, let's remove it.

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.

Source Roadmap:
