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
