[openib-general] [PATCH]libibcm: updated README for device node configuration

[William Jordan]

Libor,

Ignore this patch. I'll submit a different one to change
the ib_ucm device node from /dev/infiniband/cm
to /dev/infiniband_cm. This makes the udev setup
unnecessary.

And, this probably wasn't the right README file for the udev
rules anyway. They belong with the module, not with the library,
as pointed out by Tom.
