The patch series adds Solarflare libefx-based network PMD.

This version of the driver supports Solarflare SFN7xxx and SFN8xxx
families of 10/40 Gbps adapters.

libefx is a platform-independent library to implement drivers for
Solarflare network adapters. It provides unified adapter family
independent interface (if possible). FreeBSD [1] and illumos [2]
drivers are built on top of the library.

The patch series could be logically structured into 5 sub-series:
 1. (1) add the driver skeleton including documentation
 2. (2-30) import libefx and include it in build with the latest patch
 3. (31-42) implement minimal device level operations in steps
 4. (43-50) implement Rx subsystem
 5. (51-55) implement Tx subsystem

Functional driver with multi-queue support capable to send and receive
traffic appears with the last patch in the series.

The following design decisions are made during development:

 1. Since libefx uses positive errno return codes, positive errno
    return codes are used inside the driver and coversion to negative
    is done on return from eth_dev_ops callbacks. We think that it
    is the less error-prone way.

 2. Own event queue (a way to deliver events from HW to host CPU) is
    used for house-keeping (e.g. link status notifications), each Tx
    and each Rx queue. No locks on datapath are requires in this case.

 3. Alarm is used to periodically poll house-keeping event queue.
    The event queue is used to deliver link status change notifications,
    Rx/Tx queue flush events, SRAM events. It is not used on datapath.
    The event queue polling is protected using spin-lock since
    concurrent access from different contexts is possible (e.g. device
    stop when polling alarm is running).
