request for configurable transaction packet MID #6

Closed mogar closed 2 years ago

mogar commented 4 years ago

In our use case, we want to use CFDP to send files from CPU1 to CPU2 and from CPU1 to Ground. The two CPUs are connected via SBN, and the connection between CPU1 and the ground station is through TO and CI.

I had thought to use the MID of CFDP packets to filter which packets are let through TO and SBN. By setting up CF with two input channels and two output channels, each using separate MIDs, I could set TO to only listen for packets from one channel and SBN to listen for packets on the other CF channel.

It looks like all CFDP transfer packets use the CF_TRANS_TLM_MID, and that’s not configurable. Would it be possible to add a configuration value in cf_cfgtable to set MID for output channels, similar to what is done for the input channels?

Alternatively, is there a more standard way to do what I'm attempting?

Input/output MID configuration was done as part of v3 updates.
