You'd have to write your own driver to do it...

Isn't there usually a single board acting as master, and all the other
boards are children of it?  There has to be some sort of arbitrator...

You could possibly have a master/slave relationship, where the slaves
all present a pci device interface with memory buffer to stick received
packets, and then the master provides a way to program the slaves
where to stick packets in it's memory buffer for transmitted packets..

I've never worked with CompactPCI, so take the above with a grain of
salt..
