Arnd Bergmann b72d745120 staging: fsl-dpaa2/eth: add ETHERNET dependency
The new driver cannot link correctly when the netdevice infrastructure
is disabled:

This adds a dependency on NETDEVICES and ETHERNET.

Ioana Radulescu 6e2387e8f1 staging: fsl-dpaa2/eth: Add Freescale DPAA2 Ethernet driver
Introduce the DPAA2 Ethernet driver, which manages Datapath
Network Interface (DPNI) objects discovered on the MC bus.

In addition to DPNIs, the Ethernet driver uses several other
MC objects to build a network interface abstraction: buffer
pools (DPBPs), I/O Portals (DPIOs) and concentrators (DPCONs).

A more detailed description of the driver can be found in the
associated README file.
