[RFC][PATCH 00/50] set addr_assign_type to NET_ADDR_RANDOM if a random mac address get assigned to a netdevice

[Danny Kukawka]

The information if a device has a random MAC address is exported
to the userspace via /sys/class/net/*/addr_assign_type, which
export net_device->addr_assign_type.

Currently only a few driver really use dev_hw_addr_random() to
set addr_assign_type correctly to NET_ADDR_RANDOM.

This patch change the drivers which set random addresses to
change also addr_assign_type to NET_ADDR_RANDOM.

To reflect if the MAC was changed from userspace via SIOCSIFHWADDR,
which means it's no longer a random address set by the kernel,
this patch remove NET_ADDR_RANDOM from addr_assign_type in this
case.

With this patch tools from userspace can now detect devices with
random MAC addresses and change them to persistent addresses if
needed (as e.g. in case of smsc95xx on PandaBoard).

Maybe it makes sense to introduce a new state for addr_assign_type
to reflect the fact, that the MAC address was changed via a ioctl
from user space, e.g, with NET_ADDR_USERSPACE ?
