Subject: [dpdk-dev] [PATCH v2 28/30] net/ixgbe/base: add write flush required by Inphi PHY
Date: Wed, 21 Dec 2016 17:48:12 +0800 [thread overview]
Message-ID: <1482313694-31602-29-git-send-email-wei.dai@intel.com> (raw)
In-Reply-To: <1482313694-31602-1-git-send-email-wei.dai@intel.com>
This patch updates the configuration of PHY from Inphi (www.inphi.com)
to flush the register write with a reg read.
The Inphi PHY is configured in ixgbe_setup_mac_link_sfp_x550a.
The Inphy PHY setup flow has been updated to read configuration reg,
write only linear/non-linear, and then read (write flush).
