Ok, i've read the release and component notes for the MDIO. nice job.
this is only part of an MII/RMII solution. is the other coming very soon or do we start to roll our own? do we think a set of UDBs ( 2 or 4?) can keep up with 25/50Mhz ethernet traffic needed for MII/RMII? by the time we are done a full MII/RMII how many UDBs will be used up? will we have any left to do any work with the data?
