L2TP does not allow changing mac address at all right now. Only drivers that use eth_mac_addr, can take advantage of the flag. Looking around here are the other places that could use it. vxlan, xen-netfront?, gre, gre6, virtio_net?, hyperv? Also the following look buggy. c2 allows changing mac address but never tells hardware? isdn/hysdn_net.c allows setting mac address but then resets it card value in net_open xpnet allows setting address but it looks like it fixed by hardware ipddp allows ethernet address but protocol is not ethernet -- 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
