[Linaro-uefi] [PATCH v6 1/2] Drivers/Net: Create Pp2Dxe driver

From: Bartosz Szczepanek bsz@semihalf.com

Pp2Dxe supports Marvell PP2 NIC. It comprise up to 3 ports in a single unit (1x 10G and 2x 2.5G). Also parser and hardware buffer manager offload engines support are enabled, as their usage is obligatory.

EFI_SIMPLE_NETWORK_PROTOCOL is implemented for configurable number of interfaces via PCD.

This patch introduces also an OS-independent library with the configuration routines of the PP2 NIC. It is obtained from Marvell and adjusted to EDK2 coding style.
