Well, we (CentOS) are using a gluster setup on top of Infiniband, but
we're just using the default mlx4_ib kernel module that is included with
the kernel shipped with 6.7
(/lib/modules/2.6.32-573.22.1.el6.x86_64/kernel/drivers/infiniband/hw/mlx4/mlx4_ib.ko)
so nothing to be done at the kernel/initrd level.

Is there a reason why you needed a different version ?

PS : the IB HBA model we have in those servers is the following one :
81:00.0 InfiniBand: Mellanox Technologies MT25418 [ConnectX VPI PCIe 2.0
2.5GT/s - IB DDR / 10GigE] (rev a0)
