> There exists an intermittent bug which causes the 'Link Detected'
> field reported by the 'ethtool <iface>' command to be 'Yes' when in fact,
> there is no link. This patch fixes the problem by enabling temporary link
> polling when i40e_get_link_status returns an error. This causes the driver to
> remember that an admin queue command failed and polls, until the function
> returns with a success.
