help
PPSI is able to directly emit and receive tagged frames,
with some architectures (if you see this option, it means
the architecture you selected has such support). A
designated master port can send announce on several VLANs,
but the other roles (designated slave or auto) can only bind
to a single VLAN. This choice is a tradeoff between code
complexity and flexibility.
Please note that you can always create several PTP ports that
act on different VLANs on the same physical port, and you can
also run VLAN support in your OS without special PPSI code.
Please see the PPSI documentation for details.

help
This configuration option is mainly used to support
the special case of 1 VLAN per port, useful for
microcontroller-class architectures. Hosted builds
feature a bigger default, because they have no size constraints.
