Merge branch 'octeontx2-trusted-vf'

Naveen Mamindlapalli says:

====================
octeontx2: Add trusted VF support

This series adds support for trusted VF. The trusted VF support
allows VFs to perform priviliged operations such as setting VF
interface in promiscuous mode, all-multicast mode and also
changing the VF MAC address even if it was asssigned by PF.

Patches #1 and #2 provides the necessary functionality for supporting
promiscuous and multicast packets on both the PF and VF.

Patches #3 and #4 enable trusted VF configuration support.
====================
