Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends
on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a
link error when another driver using it is built-in. The
INFINIBAND_ADDR_TRANS dependency is insufficient here as this is
a 'bool' symbol that does not force anything to be a module in turn.

The NVM Express driver is for solid state drives directly
|
|
connected to the PCI or PCI Express bus. If you know you
|
|
don't have one of these, it is safe to answer N.

To compile this driver as a module, choose M here: the

module will be called nvme.

This provides support for the NVMe over Fabrics protocol using
|
|
the RDMA (Infiniband, RoCE, iWarp) transport. This allows you
|
|
to use remote block devices exported using the NVMe protocol set.
|
|
|
|
To configure a NVMe over Fabrics controller use the nvme-cli tool
|
|
from https://github.com/linux-nvme/nvme-cli.
|
|
|
|
If unsure, say N.
