I agree with you that it's not necessary for Ethernet/IP traffic. The point is that this isn't really Ethernet/IP traffic, it's InfiniBand/IP traffic. And there it *is* necessary. An argument can be made that the core code shouldn't assume Ethernet/IP and should support either Ethernet/IP or InfiniBand/IP. -- Doug Ledford <[email protected]> GPG KeyID: 0E572FDD
