With the OFED1.1-rc2 when I run the RDMA CM on RedHat EL4 - Update 3
I get the following warning. The application seems to work OK, 
but the warnings are concerning. 


librdmacm: couldn't read ABI version.
librdmacm: assuming: 1

It appears that the backport of the kernel module does not create the
abi_version in /sys/class/misc as the userspace code expects.
I suggest either fix the backport patch to create the abi_version or
to avoid confusion,
remove the check or the warning message from the userspace code if
the ABI does actually matches the kernel code.
