Hi Adit,
There are no QIB backports yet in OFED-4.8.
If you work on RHEL7.2 then use the following configuration parameters:
# ./configure --with-core-mod --with-user_mad-mod --with-user_access-mod 
--with-addr_trans-mod --with-mlx4-mod --with-mlx4_en-mod --with-ipoib-mod

Note: update your git trees as cxgb3/4 backports were added few days ago.

Regards,
Vladimir
