[ofa-general] ***SPAM*** libibverbs configuration directory and userspace device-specific driver

I am attempting to use libibverbs with a build from src (./configure && make
install).  However "ibv_devices" complains:

         libibverbs: Warning: no userspace device-specific driver found for
/sys/class/infiniband_verbs/uverbs0


I manually created the /usr/local/etc/libibverbs.d directory, but nothing
exists in it, and I can't seem to find any documentation on creating files
manually.

My /sys/class/infiniband_verbs/uverbs0/ directory does indeed exist:

root at leopard:/usr/src/rpm/SOURCES/libibverbs-1.1.2/src# ls -l
/sys/class/infiniband_verbs/uverbs0/
total 0
-r--r--r-- 1 root root 4096 2008-10-20 16:09 abi_version
-r--r--r-- 1 root root 4096 2008-10-20 16:19 dev
lrwxrwxrwx 1 root root    0 2008-10-20 16:09 device ->
../../../devices/pci0000:00/0000:00:1c.0/0000:03:00.0
-r--r--r-- 1 root root 4096 2008-10-20 16:09 ibdev
lrwxrwxrwx 1 root root    0 2008-10-20 16:19 subsystem ->
../../../class/infiniband_verbs
--w------- 1 root root 4096 2008-10-20 16:19 uevent
root at leopard:/usr/src/rpm/SOURCES/libibverbs-1.1.2/src#


Any ideas?

Thanks,
Mike
