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 ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
