in the case where p is not set, preventing p from being dereferenced.

There are enough register offsets to warrant being in their own header
file, and doing so logically separates them from other header file content.
They have been converted from an enumerated data type to #defines as is
done in all the other Intel wired ethernet drivers.

Currently, when the PF driver is unloaded and re-loaded while VFs are attached
to VMs, it loses control of its VFs.

The PF driver now uses the newly defined/created GET_IFACE_LIST cmd
(available in FW ver >= 4.6) to query the if_id of the VFs
(enabled in its previous life). The PF driver then uses the if_id for
further VF configuration.

The GET_IFACE_MAC_LIST cmd has also implemented in BE3 FW for PF to
query pmac-ids used by its VFs.
