Subject: [dpdk-dev] [PATCH 03/53] net/qede/base: use crc32 OSAL macro
Date: Mon, 18 Sep 2017 18:29:43 -0700 [thread overview]
Message-ID: <1505784633-1171-4-git-send-email-rasesh.mody@cavium.com> (raw)
In-Reply-To: <1505784633-1171-1-git-send-email-rasesh.mody@cavium.com>
Move ecore_crc32() macro to within base driver to qede_crc32() and use
OSAL_CRC32() where required.
