PacketTransformerInterface needed or not #8
Description
Defined PacketTransformerInterface to solve the MTU issue about which you asked on our last meeting. It will have only one distinct method from the FrameTransformerInterface -> GetReservedNumberOfBytes (thinking of a better name for this). This method will be used to the packetizer how much bytes it should leave free for the transformer to perform it's operations and not to exceed MTU.
I 'm not a big fan of that we might need this additional interface which will be fairly similar to the existing one. From the other side, i don't think that extending FrameTransformerInterface with this new method would be a clear solution, as FrameTransformerInterface would never use it for the frame-level operations.
