This more question to mellanox then to neutron community. 
I suggest that you will send me private mail regarding this issue and we can take it with the relevant people in Mellanox.

> Dear Neutron developers,
> we are building up an OpenStack (Pike) cluster based on CentOS 7.4 and
> Mellanox Ofed 4.2.
> As far as we understand Neutron rely on eIPoIB in order to manage
> Infiniband networks but unfortunately Mellanox dropped this feature for the
> new OFED versions.
> Here below the Mellanox support answer about that:
> "Please note that as of Mellanox OFED 4.0 eIPoIB is no longer supported in
> Mellanox OFED.If you wish to use it we recommend using the 3.4.X Drivers
> which still supported this feature."
> Obviously we can not use the 3.X version of OFED because is not supported
> by RHEL 7.4 and also because we don't want to stick with an old software
> version.
> Do you have any plan to overcome this issue?
> Thank you, regards
