Gleb Smirnoff a254d6870e carp: isolate VRRP from CARP
There is only one functional change here - we don't allow SIOCSVH (or
netlink request) to change sc->sc_version.  I'm convinced that allowing
such a change doesn't brings any practical value, but creates enless
minefields in front of both developers and end users (sysadmins).  If
you want to switch from VRRP to CARP or vice versa, you'd need to recreate
the VHID.

Oh, one tiny funtional change: carp_ioctl_set() won't modify any fields
if it returns EINVAL.  Previously you could provide valid advbase with
invalid advskew - that used to modify advbase and return EINVAL.

All other changes is a sweep around not ever using CARP fields when
we are in VRRP mode and vice versa.  Also adding assertions on sc_version
where necessary.

Do not send VRRP vars in CARP mode via NetLink and vice versa.  However
in compat ioctl SIOCGVH for VRRP mode the CARP fields would be zeroes.

This allows to declare softc as union and thus prevent any future logic
deterioration wrt to mixing VRRP and CARP.

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.
