PCR_MATRIX field was set to all 1's when VLAN filtering is enabled, but
was not reset when it is disabled, which may cause traffic leaks:
ip link add br0 type bridge vlan_filtering 1
ip link add br1 type bridge vlan_filtering 1
ip link set swp0 master br0
ip link set swp1 master br1
ip link set br0 type bridge vlan_filtering 0
ip link set br1 type bridge vlan_filtering 0
# traffic in br0 and br1 will start leaking to each other
As port_bridge_{add,del} have set up PCR_MATRIX properly, remove the
PCR_MATRIX write from mt7530_port_set_vlan_aware.

commit 38152ea37d8bdaffa22603e0a5b5b86cfa8714c9 upstream.
Currently, setting a bridge's self PVID to other value and deleting
the default VID 1 renders untagged ports of that VLAN unable to talk to
the CPU port:
bridge vlan add dev br0 vid 2 pvid untagged self
bridge vlan del dev br0 vid 1 self
bridge vlan add dev sw0p0 vid 2 pvid untagged
bridge vlan del dev sw0p0 vid 1
# br0 cannot send untagged frames out of sw0p0 anymore
That is because the CPU port is set to security mode and its PVID is
still 1, and untagged frames are dropped due to VLAN member violation.
Set the CPU port to fallback mode so untagged frames can pass through.

[ Upstream commit 5e5502e012b8129e11be616acb0f9c34bc8f8adb ]
When a client moves from a DSA user port to a software port in a bridge,
it cannot reach any other clients that connected to the DSA user ports.
That is because SA learning on the CPU port is disabled, so the switch
ignores the client's frames from the CPU port and still thinks it is at
the user port.
Fix it by enabling SA learning on the CPU port.
To prevent the switch from learning from flooding frames from the CPU
port, set skb->offload_fwd_mark to 1 for unicast and broadcast frames,
and let the switch flood them instead of trapping to the CPU port.
Multicast frames still need to be trapped to the CPU port for snooping,
so set the SA_DIS bit of the MTK tag to 1 when transmitting those frames
to disable SA learning.

Andrew reported:
After a number of network port link up/down changes, sometimes the switch
port gets stuck in a state where it thinks it is still transmitting packets
but the cpu port is not actually transmitting anymore. In this state you
will see a message on the console
"mtk_soc_eth 1e100000.ethernet eth0: transmit timed out" and the Tx counter
in ifconfig will be incrementing on virtual port, but not incrementing on
cpu port.
The issue is that MAC TX/RX status has no impact on the link status or
queue manager of the switch. So the queue manager just queues up packets
of a disabled port and sends out pause frames when the queue is full.
Change the LINK bit to reflect the link status.

The MediaTek MT7621 SoC device contains a 7530 switch, and the existing

The bulk of the changes required stem from the 7621 having different
regulator and pad setup. The existing setup of these in the 7530
driver appears to be very specific to its implemtation in the Mediatek
7623 SoC. (Not entirely surprising given the 7623 is a quad core ARM
based SoC, and the 7621 is a dual core, dual thread MIPS based SoC).
Create a new devicetree type, "mediatek,mt7621", to support the 7530
switch in the 7621 SoC. There appears to be no usable ID register to
distinguish it from a 7530 in other hardware at runtime. This is used
to carry out the appropriate configuration and setup.

MT7530 can treat each port as either VLAN-unaware port or VLAN-aware port
through the implementation of port matrix mode or port security mode on
the ingress port, respectively. On one hand, Each port has been acting as
the VLAN-unaware one whenever the device is created in the initial or
certain port joins or leaves into/from the bridge at the runtime. On the
other hand, the patch just filling the required callbacks for VLAN
operations is achieved via extending the port to be into port security
mode when the port is configured as VLAN-aware port. Which mode can make
the port be able to recognize VID from incoming packets and look up VLAN
table to validate and judge which port it should be going to. And the
range for VID from 1 to 4094 is valid for the hardware.

MT7530 is a 7-ports Gigabit Ethernet Switch that could be found on

includes 7-port Gigabit Ethernet MAC and 5-port Gigabit Ethernet PHY.
Among these ports, The port from 0 to 4 are the user ports connecting
with the remote devices while the port 5 and 6 are the CPU ports
connecting into Mediatek Ethernet GMAC.
For port 6, it can communicate with the CPU via Mediatek Ethernet GMAC
through either the TRGMII or RGMII which could be controlled by phy-mode
in the dt-bindings to specify which mode is preferred to use. And for
port 5, only RGMII can be specified. However, currently, only port 6 is
being supported in this DSA driver.
The driver is made with the reference to qca8k and other existing DSA
driver. The most of the essential callbacks of the DSA are already
