[dpdk-dev] [PATCH] net/ixgbe: fix link state timing issue on fiber ports

With some models of fiber ports (e.g. X520-2 device ID 0x10fb), it is possible when a port is started to experience a timing issue which prevents the link from ever being fully set up. In ixgbe_dev_link_update_share(), if the media type is fiber and the link is down, a flag (IXGBE_FLAG_NEED_LINK_C

This issue is firstly observed with an ixgbe NIC in VPP project, which is software switching application based on DPDK. There's a daemon thread running in background keeping polling hardware link status, using ixgbe_dev_link_update_share(). Once flag IXGBE_FLAG_NEED_LINK_CONFIG is set, ixgbe_dev_
