+Subject: [PATCH] ixgbe: wait longer for link after fiber MAC setup
+
+After setting up the link on a fiber port, the maximum wait time for
+the link to come up is 500 ms in ixgbe_setup_mac_link_multispeed_fiber().
+On an x550 SFP+ port, this is often not sufficiently long for the link
+to come up. This can result in never being able to retrieve accurate
+link status for the port using rte_eth_link_get_nowait().
+
+Increase the maximum wait time in ixgbe_setup_mac_link_multispeed_fiber()
+to 1 s.
+
+Bugzilla ID: 69
+Fixes: f3430431abaf ("ixgbe/base: add SFP+ dual-speed support")
