The mlx4 driver produces a link error when it is configured as built-in while CONFIG_INFINIBAND_USER_ACCESS is set to =m: drivers/infiniband/hw/mlx4/main.o: In function `mlx4_ib_mmap': main.c:(.text+0x1af4): undefined reference to `rdma_user_mmap_io' The same function is called from mlx5, which already has a dependency to ensure we can call it, and from hns, which appears to suffer from the same problem. This adds the same dependency that mlx5 uses to the other two.

This driver provides low-level InfiniBand support for

This is required to use InfiniBand protocols such as

IP-over-IB or SRP with these devices.
