container with ofed driver will see all ib cards of the host

[davidstack]

when we run a container with ofed driver, we can find all the ib cards in the container, is there a method that we can only see one ib card?, just like nvidia-docker
when we set NVIDIA_VISIBLE_DEVICE env , we we only see the GPU card which is set in this env

Can you elaborate why this is need? Mellanox driver is per all nic host

[davidstack]

when we use sr-iov to the ib card,just as one PF to nine PF. we will see ten ib cards using the ibstat command. when we allocate one vf to the docker container . i think we should see only one ib card(one vf of the pf), but now.we will see all the ib cards (vf and pf) in the container.

the driver container is not intended to be used as a base image for a workload.
it is intended to run on the host, loading the relevant kernel modules.
