From: Matthew Smith Date: Mon, 16 Jul 2018 16:36:04 +0000 (-0500) Subject: net/ixgbe: wait longer for link after fiber MAC setup X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=64f1c8539c8c;p=dpdk.git net/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.
