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.
