Subject: [PATCH 0/7] RDMA/rxe: Cleanup ICRC
Date: Tue, 29 Jun 2021 15:14:05 -0500 [thread overview]
Message-ID: <20210629201412.28306-1-rpearsonhpe@gmail.com> (raw)
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
