+Subject: [PATCH] net/i40e: fix link management
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Previously, there was a known issue "On Intel® 40G Ethernet
+Controller stopping the port does not really down the port link."
+
+There were two reasons why the port was always kept up.
+1. Old firmware versions had issues when "Set PHY config command"
+   was used on 40G NICs.
+2. The kernel i40e driver didn't call "Set PHY config command" when
+   ifconfig up/down was used, it assumes the link is always up. But
+   in DPDK, ports are forced down when an applications quits. So if
+   the port is then switched to being controlled by kernel the driver,
+   the port can not be brought up through "ifconfig <ethx> up".
+
+This patch fixes this issue by adding in "Set PHY config command"
+into our driver. This is now possible because with newer firmware
+there is no longer a problem using this command.
+
+With this fix, after DPDK quit, if the port is switched to being used
+by the kernel driver, "ethtool -s <ethx> autoneg on" can be used to
+turn on the auto negotiation, and then port can be brought up through
+"ifconfig <ethx> up".
+NOTE: requires kernel i40e driver version >= 1.4.X
+
+Fixes: 2f1e22817420 ("i40e: skip link control as firmware workaround")
+Fixes: 16c979f9adf2 ("i40e: disable setting of PHY configuration")
