VMware expects that certain kind of configurations made on the VFs are
authorized by the ESXi before these are applied e.g. assigning a MAC
address to the VF, setting MTU etc. Firmware supports a feature called
MCDI proxy which will be used to implement this authorization check.
The proxy auth module is governed by EFSYS_OPT_MCDI_PROXY_AUTH switch.
This patch adds the framework for proxy auth module along with the APIs
required for SR-IOV initialization.

Implement the framework for Enterprise Virtual Briding (EVB) module.
SR-IOV augments the software virtual switch with NIC capabilities
supported from EVB module.
Further patches will add APIs to create and destroy EVB switching
hierarchy required for SR-IOV and APIs to set vPort properties like MAC,
VLAN etc.

HW Rx descriptor represents many contiguous packet buffers which
follow each other. Number of buffers, stride and maximum DMA
length are setup-time configurable per Rx queue based on provided
mempool. The mempool must support contiguous block allocation and
get info API to retrieve number of objects in the block.

Equal stride super-buffer Rx mode is supported by DPDK firmware
variant. One Rx descriptor provides many Rx buffers to firmware.
Rx buffers follow each other with specified stride.
Also it supports head of line blocking with timeout to address
drops when no Rx descriptors are available. So it gives extra time
to the driver to provide Rx descriptors before drop.

FW subvariants allow to tweak NIC global features. For example,
if no drivers require checksumming on transmit, it may be disabled

EFSYS_MEM_SIZE() reports the DMA mapped size of an efsys_mem_t
allocated region (the allocation size may be different due to
memory allocator and DMA alignment restrictions).
This ensures that common code internals have explicit knowledge
of the usable size of DMA mapped memory regions.

The patch is to add support for MCDI proxy which comes in
useful, particularly, while running over VF: few commands
will normally fail with EPERM, but in some cases the host
driver (i.e. running over the corresponding PF, typically,
within a hypervisor) may set itself as a proxy to conduct
authorization for the commands coming from VFs; these are
forwarded to the corresponding access control application
which may decline or approve authorization by replying to
the requests; all in all, the guest driver has to process
the replies forwarded back by the firmware MC in order to
give up gracefully (by setting return code which could be
understood by 'libefx') or re-issue the original commands
