Can you explain which GMAC are you targeted ? A driver which support some Synopsys GMAC IP already exists. It support GMAC 3.5, 3.7, 4.0, 4.10 versions. You can find it in: drivers/net/ethernet/stmicro/stmmac/. When I look at all files your gonna to create, it looks like to ones in stmmac driver so maybe you could easily add your IP inside stmmac driver. Note that an other driver is existing for synopsys GMAC 4.0 IP. it is located in drivers/net/ethernet/synopsys/dwc_eth_qos.c and coming from AXIS guys. A task is ongoing to only have stmmac driver so it should be harmful to create a new one.
