2019-04-30net: dsa: b53: Use vlan_filtering property from dsa_switchVladimir Oltean
While possible (and safe) to use the newly introduced dsa_port_is_vlan_filtering helper, fabricating a dsa_port pointer is a bit awkward, so simply retrieve this from the dsa_switch structure.

2019-02-15net: dsa: b53: Properly account for VLAN filteringFlorian Fainelli
VLAN filtering can be built into the kernel, and also dynamically turned on/off through the bridge master device. Allow re-configuring the switch appropriately to account for that by deciding whether VLAN table (v_table) misses should lead to a drop or forward.

2018-09-06net: dsa: b53: Add SerDes supportFlorian Fainelli
Add support for the Northstar Plus SerDes which is accessed through a special page of the switch. Since this is something that most people probably will not want to use, make it a configurable option with a default on ARCH_BCM_NSP where it is the most useful currently. The SerDes supports both SGMII and 1000baseX modes for both lanes, and 2500baseX for one of the lanes, and is internally looking like a seemingly standard MII PHY, except for the few bits that got repurposed.

2018-06-06net: dsa: b53: Fix for brcm tag issue in Cygnus SoCArun Parameswaran
In the Broadcom Cygnus SoC, the brcm tag needs to be inserted in between the mac address and the ether type (should use 'DSA_PROTO_TAG_BRCM') for the packets sent to the internal b53 switch. Since the Cygnus was added with the BCM58XX device id and the BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is broken, due to the incorrect brcm tag location. Add a new b53 device id (BCM583XX) for Cygnus family to fix the issue. Add the new device id to the BCM58XX family as Cygnus is similar to the BCM58XX in most other functionalities.

Upon reception of the NETDEV_CHANGEUPPER, a leaving port is already unbridged, so reflect this by assigning the port's bridge_dev pointer to NULL before calling the port_bridge_leave DSA driver operation. Now that the bridge_dev pointer is exposed to the drivers, reflecting the current state of the DSA switch fabric is necessary for the drivers to adjust their port based VLANs correctly. Pass the bridge device pointer to the port_bridge_leave operation so that drivers have all information to re-program their chips properly, and do not need to cache it anymore.
