drivers/net: Add device index for multiple NIC cards
This patch adds a member device_index to r8168 chip information which allows driver to identify which NIC card requests MAC address. In this implementation, only 10 NIC cards are supported, the device index is in the range of 0 to 10. Regarding to MAC address mapping, when there is only one NIC on DUT, it is treated as a special case mapping to "ethernet_mac" in VPD for backward compatibility. When there are multiple NICs on DUT, they are mapping to "ethernet_macN" where N is [0-9]. Device tree configuration: For single NIC: .device_index = "0", maps to "ethernet_mac" For multiple NICs: .device_index = "[1-10]", maps to "ethernet_mac[device_index - 1]" BUG=b:69950854 BRANCH=None TEST=Added device_index = [0-10] under /drivers/net in device tree && Programmed the mac address to VPD in shell vpd -s ethernet_mac=<mac address> or vpd -s ethernet-mac[0-9]=<mac address> && reboot the system. Ensure the MAC address was fetched correctly by ifconfig command.
