Minwoo Im 79fd751d61 nvme: tcp: selects CRYPTO_CRC32C for nvme-tcp
The tcp host module is now taking those APIs from crypto ahash:
	(1) crypto_ahash_final()
	(2) crypto_ahash_digest()
	(3) crypto_alloc_ahash()

nvme-tcp should depends on CRYPTO_CRC32C.

depends on PCI && BLOCK
select NVME_CORE
---help---
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.
config NVME_MULTIPATH
bool "NVMe multipath support"
depends on NVME_CORE
---help---
This option enables support for multipath access to NVMe
subsystems. If this option is enabled only a single
/dev/nvmeXnY device will show up for each NVMe namespaces,
even if it is accessible through multiple controllers.

select NVME_FABRICS
select SG_POOL
help
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.
