How to get wimax device Mac address on linux

The only way to find the original MAC address is to use the same method the network card driver does - unfortunately, I don't believe there is a generic way to tell the driver to provide its MAC address 'as provided by the hardware'. Memcpy(mac, ifr.ifr_hwaddr.sa_data, IFHWADDRLEN) #include /* for the glibc version number */ I suppose it should be possible to write C code for it, below code gives my current MAC but not the original MAC: #include /* Standard I/O */ Is there any utility or command for that? How do I find the original MAC address? There must be a way to find it, because it is still burned permanently into the card, but I can't find a tool to read the burned in address. Or setting it 'permanently' using /etc/sysconfig/network-scripts/ifcfg-eth0. I understand how to find the current MAC address using ifconfig.īut the address can be changed, say by using ifconfig eth0 hw ether uu:vv:ww:yy:xx:zz I'm trying to figure out how to find the original MAC address of an Ethernet NIC on my Linux box. So once MAC address is set, commands like ifconfig don't get it from device driver accessing HW registers, but from net_device structure.Is it possible to read the MAC address from the NIC directly? I have the code below but it just reads from the layer above but not the card itself. (ndev->dev_addr dev_addr dev_addr dev_addr | * Set up unicast MAC address filter set its mac address */ If (!is_valid_ether_addr(ndev->dev_addr)) Memcpy(ndev->dev_addr, address, ETH_ALEN)

Struct axienet_local *lp = netdev_priv(ndev) 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) 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.
