As defined, this does not have an impact on IP. The consumer of these capabilities at this time is the LDoms vsw driver. The vsw driver will use this interface to steer resources to guest domains. At the time Crossbow integrates, Crossbow's mac layer will be the consumer of these capabilities as it desginates what to do with the resources of the NIU. > > Does the work this project is doing require any such changes > in IP (and have been forgotten for inclusion in the materials) > or is everything self contained within what is being defined > in the mac changes?

During implementation, we discovered the we needed an additional interface for the MAC_CAPAB_SHARE capability to handle the of constraints being placed on a share. For example, only certain RX and TX DMAs can be assigned to a share. Or, shares have constraints to how many or how few DMA resources can be added to them. The updated specification has "!" at the beginning of the line to indicate where the change was made. I would still like to close on this case on 4/16/2008. If you have any concerns or questions please let's address them quickly. Thanks, Michael
