[for-next,resending,0/5] RDMA/rxe: Cleanup ICRC

Message

Bob Pearson June 29, 2021, 8:28 p.m. UTC

This series of patches cleans up the code in the rdma_rxe driver that
handles computing and checking of the ICRC checksum in RoCE packets.
All the ICRC related code is isolated in the file rxe_icrc.c.
The overall performance is modestly improved. (ib_write_bw loopback
performance is increased from 2.7GB/sec to 2.8GB/sec.) There is no
change required to the user space provider.

Bob Pearson (5):
  RDMA/rxe: Move ICRC checking to a subroutine
  RDMA/rxe: Move rxe_xmit_packet to a subroutine
  RDMA/rxe: Move ICRC generation to a subroutine
  RDMA/rxe: Move rxe_crc32 to a subroutine
  RDMA/rxe: Move crc32 init code to rxe_icrc.c
