From ba9b381c532fe57c726752b7db0ab45ab7726c90 Mon Sep 17 00:00:00 2001 From: Matthew Smith Date: Fri, 13 Jul 2018 16:35:57 -0500 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.
