Subject[PATCH v1] tg3: optionally use eth_platform_get_mac_address() to get mac address
Date
This function will try to determine the mac address via the devicetree,
or via an architecture-specific method (e.g. a PROM on SPARC).

The SPARC-specific code in this driver (#ifdef SPARC) did exactly this,
and is therefore removed.

Note that you can now specify the tg3 mac address via the devicetree,
on any platform, not just SPARC:

Devicetree example:
(see Documentation/devicetree/bindings/pci/pci.txt)

&pcie {
host@0 {
#address-cells = <3>;
#size-cells = <2>;
reg = <0 0 0 0 0>;
bcm5778: bcm5778@0 {
reg = <0 0 0 0 0>;
mac-address = [CA 11 AB 1E 10 01];
};
};
};
