It's quite useful to be able to trigger LEDs based on network activity,
similar mechanisms exist in routers and gateway devices.
I am looking to mainline a patch that has existed out of tree for
some time in OpenWRT/LEDE.
The patch has been updated and restructured and most of the issues raised
in the initial submission have been addressed [1].
I am also including the netdev mailing list as it was suggested previously
that if there is no activity the interval will still run and is wasteful
