[U-Boot] [PATCH v2] net: usb: r8152: Add DM support
Stefan Roese
sr at denx.de
Wed Jun 29 07:58:05 CEST 2016
Add support for driver model, so that CONFIG_DM_ETH can be defined and
used with this driver.
This patch also adds the read_rom_hwaddr() callback so that the ROM MAC
address will be used to the DM part of this driver.

v2:
- Return all errors from usb_ether_receive() in r8152_eth_recv()
- Use ENOSPC as error return code in r8152_eth_recv() instead of EINVAL
- Return error if rtl_ops_init() fails
