[PATCH 03/33] netdev: expose ethernet address primitives

[Stephen Hemminger <shemminger@vyatta.com>]

[-- Attachment #1: eth-netdev-ops.patch --]
[-- Type: text/plain, Size: 2708 bytes --]

When ethernet devices are converted, the function pointer setup
by eth_setup() need to be done during intialization.
