Subject: [dpdk-dev] [PATCH v2 08/30] net/ixgbe/base: cleanup X540 checksum calculation
Date: Wed, 21 Dec 2016 17:47:52 +0800 [thread overview]
Message-ID: <1482313694-31602-9-git-send-email-wei.dai@intel.com> (raw)
In-Reply-To: <1482313694-31602-1-git-send-email-wei.dai@intel.com>
The variable checksum_last_word is used only for bounds check.
So remove this variable and use IXGBE_EEPROM_CHECKSUM directly.
