[PATCH 00/12] Part 2: check given MAC address, if invalid return -EADDRNOTAVAIL

[Danny Kukawka]

Second Part of series patches to unifiy the return value of 
.ndo_set_mac_address if the given address isn't valid.

These changes check if a given (MAC) address is valid in 
.ndo_set_mac_address, if invalid return -EADDRNOTAVAIL 
as eth_mac_addr() already does if is_valid_ether_addr() fails.

These patches are against net-next.

    return -EADDRNOTAVAIL

This patch series looks wrong - you cannot go blindly applying ethernet
mac address tests to device drivers without checking if they are using
802.11 type addressing at the physical level.

Why not just fix dev_set_mac_address() and make do_setlink() use that?
Checks are specific to address family, not device model I assume.

Another netdev project?

[Joe Perches]

It seems you're doing some nice cleanups.

Maybe you could investigate consolidating all the
various link state change messages into a
.ndo_link_state_changed function so that perhaps a
standard dmesg mechanism could be used.

Indeed, why can't this be done in one single place, instead of sprinkling these
checks over all drivers, missing all out-of-tree (note: I don't care) and all
soon-to-be-submitted drivers?

Wouldn't it be better to do this in one place? dev_set_mac_address()
seems like a good place...
