[openib-general] uDAPL on OpenIB gen2

[Aniruddha Bohra]

Hello
    I enabled the DAT_DBG_TYPE=0xffff and DAPL_DBG_TYPE=0xffff.
That gave me the answer.

    Basically libibcm is not linked with dapltest and when the dat_provider
tries to load, and calls ib_cm_send_req, it fails.

    So, just adding -libcm to the dapltest link commands make it work.
It would be great if it could be added to the svn repo.

Thanks for your help.

Regards,
Aniruddha
