Like David Ahern I am strongly against the proliferation of sysfs files
attached to network devices and the per-netdevice costs associated with
that.
However, dealing with that is a longer term issue that nobody has a clear
plan for. Therefore I cannot reject this change on that basis alone.
The information is useful, so applied, thanks.
