Commit 5882d526 authored by David S. Miller's avatar David S. Miller

Merge branch 'net-dsa-bcm_sf2-Store-rules-in-lists'

Florian Fainelli says:

====================
net: dsa: bcm_sf2: Store rules in lists

This patch series changes the bcm-sf2 driver to keep a copy of the
inserted rules as opposed to using the HW as a storage area for a number
of reasons:

- this helps us with doing duplicate rule detection in a faster way, it
  would have required a full rule read before

- this helps with Pablo's on-going work to convert ethtool_rx_flow_spec
  to a more generic flow rule structure by having fewer code paths to
  convert to the new structure/helpers

- we need to cache copies to restore them during drive resumption,
  because depending on the low power mode the system has entered, the
  switch may have lost all of its context
