[dpdk-dev] [PATCH] net/ixgbe: update data->eth_link status on start

[Chas Williams <3chas3@gmail.com>]

From: "Charles (Chas) Williams" <chas3@att.com>

dev->data->eth_link isn't updated until the first interrupt.  If a
link is carrier down, then this interrupt may never happen.  Before we
finished starting the PMD, call ixgbe_dev_link_update() to ensure we
have a valid status.
