Hmm, so I added that line to rdma-description.rules, generated and installed
the rpms. udevadm shows me this:

$> udevadm info /sys/class/infiniband/vmw_pvrdma0 | grep -i id_rdma
E: ID_RDMA_ROCE=1

I'm guessing thats the output you're looking for?

Sorry I'm not an expert on the udev stuff but what does the RDMA_ROCE environment
correspond to here - just the various modules to be loaded and/or something else?

Thanks,
Adit
