Subject: [dpdk-dev] [PATCH v3 2/3] ixgbe: Bug fix: Properly configure Rx CRC stripping for x540 devices
Date: Thu, 12 Mar 2015 23:17:31 +0200 [thread overview]
Message-ID: <1426195052-4640-3-git-send-email-vladz@cloudius-systems.com> (raw)
In-Reply-To: <1426195052-4640-1-git-send-email-vladz@cloudius-systems.com>
According to x540 spec chapter 8.2.4.8.9 CRCSTRIP field of RDRXCTL should
be configured to the same value as HLREG0.RXCRCSTRP.
Clearing the RDRXCTL.RSCFRSTSIZE field for x540 is not required by the spec
but seems harmless.
