ixgbe patch for link status updates
An x550 with SFP+ interfaces attached to some switches can have problems bringing the port up. After configuring the link, there is a wait for 500 ms for the link to come up. Some switches don't bring their ports up that quickly. So the link is never observed to come up and is reconfigured again the next time dpdk_update_link_state() is called. Subsequent attempts time out also indefinitely. Instead of waiting through 5 iterations of a 100 ms delay, wait through 10 iterations. The i40e PMD does this when updating link status. This issue & patch will be reported to Intel so this or some better solution can be applied upstream in the future.
