ehea: IBM eHEA Ethernet Device Driver

Hello,

this is the first version of the IBM eHEA Ethernet Device Driver. It supports a new IBM ethernet chip on System p.

Main functionality including broadcast multicast and some parts of ethtool already work.

Things we're still working on:
- vlan support
- performance improvements in SMP systems
- kernel coding style

This code is not ready for kernel inclusion as is, but we definetly want to get there.

The patch series consists of 4 patches
01: interfaces to network stack and headers
02: pHYP interface
03: queue managment
04: Kconfig and Makefile
