Subject: [dpdk-dev] [PATCH] i40e: Use one bit flag for all hardware detected RX packet errors
Date: Wed, 26 Nov 2014 14:07:12 +0800
Message-ID: <1416982032-28519-1-git-send-email-helin.zhang@intel.com> (raw)

There were some bit flags of 0 for RX packet errors detected by hardware.
Actually only one bit of error flag is enough for all hardware detected
RX packet errors.
