Are you looking to have a sort of control block that can apply
configuration settings to these packet deframers? Either once at
init-time or at runtime based on some conditions? If so, this also might
make sense for you:

In GRAS, your deframers would register calls for configuring packet
reception:

In the top block, when you connect flows, you can also register the
blocks into a tree. The control block could then find the deframers at
runtime and apply new settings dynamically:

Its all GRC friendly and thread safe. You could do this with messages
too, it really depends what works best or makes the most sense. Anyway,
I have just been thinking about this kind of stuff and I wanted to share.
