Staging: Netlogic XLR/XLS GMAC driver
Add support for the Network Accelerator Engine on Netlogic XLR/XLS MIPS SoCs. The XLR/XLS NAE blocks can be configured as one 10G interface or four 1G interfaces. This driver supports blocks with 1G ports. Signed-off-by: Ganesan Ramalingam <ganesanr@broadcom.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
