[PATCH v4 net-next 3/7] net: mvneta: Use cacheable memory to store the rx buffer virtual address

Until now the virtual address of the received buffer were stored in the cookie field of the rx descriptor. However, this field is 32-bits only which prevents to use the driver on a 64-bits architecture. With this patch the virtual address is stored in an array not shared with the hardware (no
