Specifically, a critical piece of the hardware is unidirectional fiber connections between independent computers, with data transmission performed using UDP to a static ARP entry. These first 2 RFC patches provide support for off-the-shelf gigabit sky2 boards. I also have another fairly trivial patch to "ethtool" which enables it to configure the new ethtool values. If these patches are acceptable, I'm going to polish up and refine a more invasive series which cleans up and extends some of the PHY ethtool handling to allow PHYs to handle the unidirectional modes in a driver-specific way. Cheers, Kyle Moffett
