Users expect that when adding a steering filter for the local MAC
address, that all the traffic directed to that address will go to some
queue.

Currently, it's not possible to configure entries in the "in use"
state, which is the normal state of the local MAC address entry (it is
the default), this patch allows to override the steering configuration
of "in use" entries, if the filter to be added match the address and
address type (source or destination) of an existing entry.

There is a bit of a special handling for entries referring to the
local MAC address, when they are removed, only the steering
configuration is reset.
