Subject: [dpdk-stable] [PATCH v2 14/30] net/ixgbe/base: fix setting unsupported autoneg speeds
Date: Wed, 21 Dec 2016 17:47:58 +0800 [thread overview]
Message-ID: <1482313694-31602-15-git-send-email-wei.dai@intel.com> (raw)
In-Reply-To: <1482313694-31602-1-git-send-email-wei.dai@intel.com>
Update ixgbe_setup_phy_link_generic that set/unset auto-negotiation.
Ensure that unsupported auto-negotiation speeds are unset.
This is necessary since the PHY NVM may advertise unsupported speeds.
Fixes: af75078fece3 ("first public release")
