Now that we are on samba 4.x, let's give SMB3 another try.
Add support for streams_xattr vfs objects in smb.conf.

This improves support for Macs using SMB.

Make both "freenas" and "truenas" targets work, just for consistency's sake.
Fix reversed logic.

This error was causing stat vol = no to be put in AFP
shares by default.  The netatalk default for this setting is yes.

I believe this is responsible for a wide range of breakage in netatalk.
This restores the correct behavior.  If you check the box labeled no stat
(which is only visible under advanced) then it will put stat vol = no in
for that share.

Otherwise, the default value for a share created with FreeNAS will be to
use the netatalk value for this field, which is stat vol = yes.
Add trafshow to the image.

A small useful utility for seeing what is doing what
on the network.

Ticket: #3812
Remove backend support for AFP share passwords

The netatalk developers say this likely doesn't work with
modern versions of OSX.  I was unable to make it work.

This only removes the option from the config file generator, it's
still in the GUI however not hooked up to anything.
