[PATCH v2 02/20] net-next: stmmac: add optional setup function

From: Corentin Labbe <clabbe.montjoie@gmail.com>
Date: 2017-03-14 14:28:38
Also in: linux-arm-kernel, linux-devicetree, lkml
Subsystem: networking drivers, stmmac ethernet driver, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

Instead of ading more ifthen logic for adding a new mac_device_info
setup function, it is easier to add a function pointer to the function
needed.
