[openib-general] Mainline 2.6.16 kernel with openib userland libraries

[Viswanath Krishnamurthy]

I tried using openib userland libraries with mainline 2.6.16  kernel but ran
into
a strange problem. A userland application which uses CM and VERBS library
which works
fine with earlier releases stopped working with no error (in API's). When I
put
the analyser on, I see the CM connect sequence is fine but when
ibv_post_send (RC send)
the DLID field in the LRH header is zero causing the packet to be dropped.

I tried mainline 2.6.16 kernel (with IB stack from kernel tree)

Any idea about the compatilibility issues ?

Thanks,
