So should I just leave the code for handling the mac_addr field from the partial pdata out or make it such that the mac_addr field is overriden if specified from the devicetree? -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I'm saying the partial pdata mac_addr is completely unused and should be removed. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

The code currently checks the mac_addr variable that is clearly zero'd out during allocation. Further code is added to bring the mac_addr from the partial pdata.
