The second  "hw = IXGBE_DEV_PRIVATE_TO_HW(dev->data->dev_private);" can be removed. :-)
And is there any other patch to use this new function ?

[PATCH v4] net/ixgbe: ping VF when PF status changes

[alexz]

From: Alex Zelezniak <alexz@att.com>

v4:
* Removed duplicate line

v3:
* Added 17.05 block to rte_pmd_ixgbe_version.map file

v2:
* Removed trailing spaces

v1:
* Implements function used by application managing PF
to inform VF when link status changes
