On OcteonTx2 silicon there two two types VFs, VFs that share the physical link with their parent SR-IOV PF and the VFs which work in pairs using internal HW loopback channels (LBK). Except for the underlying Rx/Tx channel mapping from netdev functionality perspective they are almost identical. This patch adds netdev driver support for these VFs. Unlike it's parent PF a VF cannot directly communicate with admin function (AF) and it has to go through PF for the same. The mailbox communication with AF works like 'VF <=> PF <=> AF'. Also functionality wise VF and PF are identical, hence to avoid code duplication PF driver's APIs are resued here for HW initialization, packet handling etc etc ie almost everything. For VF driver to compile as module exported few of the existing PF driver APIs.
