Bill Paul b106252c19 Implement SIOCSIFLLADDR, which allows you to change the link-level ... address on an interface. This basically allows you to do what my little setmac module/utility does via ifconfig. This involves the following changes: socket.h: define SIOCSIFLLADDR if.c: add support for SIOCSIFLLADDR, which resets the values in the arpcom struct and sockaddr_dl for the specified interface. Note that if the interface is already up, we need to down/up it in order to program the underlying hardware's receive filter. ifconfig.c: add lladdr command ifconfig.8: document lladdr command You can now force the MAC address on any ethernet interface to be whatever you want. (The change is not sticky across reboots of course: we don't actually reprogram the EEPROM or anything.) Actually, you can reprogram the MAC address on other kinds of interfaces too; this shouldn't be ethernet-specific (though at the moment it's limited to 6 bytes of address data). Nobody ran up to me and said "this is the politically correct way to do this!" so I don't want to hear any complaints from people who think I could have done it more elegantly. Consider yourselves lucky I didn't do it by having ifconfig tread all over /dev/kmem.		2000-06-16 20:14:43 +00:00
