So once MAC address is set, commands like ifconfig don't get it from device driver accessing HW registers, but from net_device structure. If you don't find a machine in the list, you need to connect to it, because it has been removed from the list because not used for a while. (ndev->dev_addr dev_addr dev_addr dev_addr | To see the MAC address of the default routers IP address, use ip neigh and look up the line with the IP address and MAC address after lladdr. * Set up unicast MAC address filter set its mac address */ ![]() If (!is_valid_ether_addr(ndev->dev_addr)) This command will list MAC address, IP address, MTU size and other information about a network interface. The number next to ether is the MAC address. All we need is to open the terminal then type ifconfig -a in the prompt. Memcpy(ndev->dev_addr, address, ETH_ALEN) The best Linux command to find MAC address is using ifconfig command. Struct axienet_local *lp = netdev_priv(ndev) If you have issues with that, you can always use the arp command. getmac /s /u /p .![]() If you are not on a domain, you may have to use the /U switch and pass the name of an administrator account on the other computer. It is handled differently on each network device depending on HW registers architecture.įor example for Xilinx AXI MAC address is written to net_device structure and specific HW registers of network controller: static void axienet_set_mac_address(struct net_device *ndev, void *address) Simply open a command prompt and type: getmac /s viper. ![]() ndo_set_mac_address = netdev_set_mac_address There is even a callback defined in net_device_ops. There is code in a network driver to access/set MAC address.
