Jeremy,

I found an explanation of netlink vs. ioctl here:
http://www.wlug.org.nz/LinuxNetlinkSockets

I assume loader, which does the initial network setup, would have to
understand the netlink method in order to grab stage2 over Infiniband
and feed it to Anaconda.  Is converting loader to use netlink on your
roadmap for FC6?
