Project information - SMBv2+

So I am found the main protocol spec existing in freebsd-src/sys/netsmb
and got the corresponding implementation from apple.

As I've never developed on FreeBSD, I am searching for a good workflow
to test builds. Right now I've build freebsd-src from git.

As far as I understand netsmb in sys is not a module build into the
kernel? Therefore I have to update kernel and install it in a test
environment for debugging. I don't want to polute my main system and
read about using bhyve as a vm system for testing. Is this the only way
or is there a smarter way getting debugging done to test my
implementation. I've never developed things on kernel-level so I got a
prog-debug cycle with high frequency for now.

(As you can see, I am starting from the beginning related to FreeBSD
development. Sry for that.)
