There was no change regarding this, you always get multiple events for
different parts of that device and need to act only on one of them. You
can probably look if $INTERFACE, or something else, only for one of the
events is set in the environment, else just exit. "udevmonitor --env"
should show the difference.
Anyway, you better move to udev rules to hook into the events, instead
of depending on the weird map stuff, which is not longer supported.
