This PR changes the wormhole_router and _adapters to use bsg_noc links on the network side. The testbenches have been updated to work with the new interface and I've tested the whole system with new links on BlackParrot in a separate branch there.

…ion makes wormhole router no longer backward compatible!

In adapter_out, would it be good to assign link_o_cast.v = 0 and link_o_cast.data = 0, just like what adapter_in is doing (link_o_cast.ready_and_rev = 0)?

looks fine. if you plan to buffer adapter in with bsg_two_fifo, it should probably go between adapter and router, not between LCE and adapter

Good call, I’ll move it there for consistency
