[Linux] Print Out the MAC address in Linux Kernel

In Linux Kernel, we want to print out the mac address information, we can use this pattern.

[sourcecode language=”c”]

printk("mac address: %02x:%02x:%02x:%02x:%02x:%02x",

node_id[0] & 0xff, (node_id[0]>>8) & 0xff,

node_id[1] & 0xff, (node_id[1]>>8) & 0xff,

node_id[2] & 0xff, (node_id[2]>>8) & 0xff);

[/sourcecode]
