Subject: [dpdk-dev] [PATCH v3 0/2] Fix CRC32c computation
Date: Fri, 19 Feb 2016 12:00:29 +0100 [thread overview]
Message-ID: <1455879631-18420-1-git-send-email-didier.pallard@6wind.com> (raw)
In-Reply-To: <1455010467-4991-1-git-send-email-didier.pallard@6wind.com>
CRC32c computation is not valid when buffer length is not a multiple of 4 bytes.
Values returned by rte_hash_crc functions does not match the one
computed by a trivial crc32c implementation.
First patch fixes crc hash function autotests, to outline the problem.
Second patch fixes CRC32c computation.
Didier Pallard (2):
test: fix CRC hash function autotest
hash: fix CRC32c computation
