Build lustre-client with ofa kernel from Mellanox 4.0-1.0.1.0 fails due to missing symbols:

---------------------------------------------------------------------------------------

I built with: --with-o2ib=/usr/src/ofa_kernel/default/

This symbols have been dropped from that version so Lustre kernel modules are not compatible to the curretn mellanox version.

I tried with MLNX_OFED_LINUX-3.4-2.0.1.0-redhat7.2-x86_64, and the build went fine.

This should be fixed in the 2.10 release - MOFED 4.0 did not exist when the 2.9 release came out. More details are in LU-9026
