It has glue layer for pci, platform, core etc, please refer this driver once before you start. You can start adding missing feature of 4.x in stmmac driver. > > (See http://lists.openwall.net/netdev/2016/02/29/127) > > The former only supports 4.x of the hardware. > > The later supports 4.x and 3.x and already has a platform glue driver > with support for several platforms, a PCI glue driver, and a core driver > with several features not present in the former (for example: TX/RX > interrupt coalescing, EEE, PTP). > > Have you evaluated both drivers?
