[dpdk-stable] [PATCH v2 1/3] net/i40e: remove duplicate code

[Qi Zhang]

Make i40e_notify_all_vfs_link_status as a wrapper of
i40e_notify_vf_link_status so duplicate code can be removed.

[Qi Zhang]

When PF notify link speed to VF, encode of link speed need to
be converted from ETH_SPEED_XXX to I40E_LINK_SPEED_XXX.
