[ewg] librdmacm examples not working under OFED 1.2 alpha

[Or Gerlitz]

I have tested RH4 U4 and to some extent also RH5 beta and see the following:

under RH4 U4
============

- rping: addr and route resolution passing, client getting reject on conn req

- udaddy: working fine on both UDP and IPOIB port spaces

- mckey: not applicable on RH4 U4 till my patch with ip_ib_mc_map is merged

under both udaddy and rping librdmacm report:

	librdmacm: couldn't read ABI version.
	librdmacm: assuming: 4

under RH5
=========

basically, the same: rping does not work, udaddy works on both port spaces.
Also was able to check mckey and it works fine on both port spaces.
The ABI error print is not seen.

The rping client/server logs are below,

Or.
