[klibc] Request: Infiniband Support in ipconfig

Right now, I am bootstrapping the initrd and kernel via gigabit ethernet and TFTP.

I use a kernel configuration option in the pxelinux configuration file to set up the IP address manually, as such: ip=

So I am not presently using DHCP on the Infiniband interface.  What I can do is set up a testbed network and move the entire boot process over to Infiniband.  I think gPXE can and does understand Mellanox Infiniband -- I've seen it enumerate my infiniband interfaces on boot.

What do you need from the packet capture, so I can better help you with this?  It seems like you'd like to see a DHCP request over Infiniband?
