If the inpcb is already bound to a local address, there is no reason to call in6_pcbladdr(). If the inpcb is already bound to a local port, there is no reason to call in_pcb_lport_dest(). In the opposite case, if the inpcb is not bound, and we are about to choose a non-conflicting local addr:port, then there is no reason to call in6_pcblookup_internal(). This change makes in6_pcbconnect() to look much more alike the IPv4 in_pcbconnect(). I tracked this strange logic all the way down to initial KAME import and failed to find any reasoning for 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.
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.
