So it looks like below,
#cat rdma.resources.verbs.list
Output:
mlx4_0 uctx ah pd cq mr mw srq qp flow
mlx4_1 uctx ah pd cq mr mw srq qp flow rss_wq

What happens if you set a limit of rss_wq to mlx4_0 in this example?
Would it fail?

Yes, In above example, mlx4_0 device didn't had support for rss_wq, so
it didn't advertise in the list file that it supports rss_wq.

I think it would be simpler for administrators if they
can configure every resource supported by uverbs. If a resource is not
supported by a specific device, you can never go over the limit anyway.

Exactly. Thats the implementation today.
