Tom Talpey fc5e1acf6a RDMA/siw: Add missing Kconfig selections 
The SoftiWARP Kconfig is missing "select" for CRYPTO and CRYPTO_CRC32C.

In addition, it improperly "depends on" LIBCRC32C, this should be a
"select", similar to net/sctp and others. As a dependency, SIW fails
to appear in generic configurations.

config RDMA_SIW tristate "Software RDMA over TCP/IP (iWARP) driver" depends on INET && INFINIBAND depends on INFINIBAND_VIRT_DMA select LIBCRC32C select CRYPTO select CRYPTO_CRC32C help This driver implements the iWARP RDMA transport over the Linux TCP/IP network stack. It enables a system with a standard Ethernet adapter to interoperate with a iWARP adapter or with another system running the SIW driver. (See also RXE which is a similar software driver for RoCE.)

The driver interfaces with the Linux RDMA stack and
implements both a kernel and user space RDMA verbs API.
The user space verbs API requires a support
library named libsiw which is loaded by the generic user
space verbs API, libibverbs. To implement RDMA over
TCP/IP, the driver further interfaces with the Linux
in-kernel TCP socket layer.
