Can we make this 'const char *key'? I know other code that calls
dbus_message_iter_get_basic() for strings doesn't do that, but I think
it should. And we shouldn't be modifying the value anyway.

Same here, let's make this 'const u8 *mask'.

I think wpa_supplicant preference is "unsigned int" rather than "uint",
but I could be wrong.

All the wpa_setup_mac_addr_rand_params() stuff could be a separate
patch in the series and might be easier to review/bisect later if
needed. I'll leave that up to Jouni though.

Ugh; future cleanup here could be to make wpa_s->mac_addrs[3][ETH_ALEN]
or something and have MAC_ADDR_RAND_* be an index into that table.
Overall LGTM after the variable type changes.
