Subject: [PATCH 0/6] RDMA: switch to using CRC32 library functions

Starting in 6.14, the crc32() and crc32c() library functions are
directly optimized for each architecture (see
https://git.kernel.org/linus/37b33c68b00089a5), and there is no longer
any need to go through the crypto API.  Therefore uses of the "crc32"
and "crc32c" crypto_shash or crypto_ahash algorithms are being replaced
with straightforward calls to crc32() and crc32c() kernel-wide.  This
patchset does this conversion in drivers/infiniband/.

Compile-tested only.

Eric Biggers (6):
  RDMA/rxe: handle ICRC correctly on big endian systems
  RDMA/rxe: consolidate code for calculating ICRC of packets
  RDMA/rxe: switch to using the crc32 library
  RDMA/irdma: switch to using the crc32c library
  RDMA/siw: fix type of CRC field
  RDMA/siw: switch to using the crc32c library
