DSA and switchdev in general gives you a linux interface per user
switch port. So you can see each interface, get stats, ethtools,
mii-tool, etc per interface. devlink is not needed for this.

I want to see each ports behind the bridge as independent ethernet
devices. If I understand RTFM only devlink may expose this
configuration.

We don't have a ndo_change_mtu callback implemented for DSA network devices but 
that is probably how we should do it. Regarding devlink, Andrew added basic 
support for it but unlike mlxsw it is currently of mild interest. Do you have 
something specific in mind with devlink?

There is no documentation from mediatek about this feature. Driver
from SDK v4.x contains only switching 19'th bit in GDMA1_FWD_CFG and
nothing more.
So, how to write patches? Peeking random bits in random SOC config registers?

To get the driver merged, it is better to start small, a minimal set
of features. Other features can be added later. If these features are
important to you, please feel free to submit patches.

It is better to move the functions around than have forward

So here you would pass priv to _mt7530_read().

This is where your need for lpriv comes, you can only pass a single
argument. But you can work around it. readx_poll_timeout is a
#define. So there is no type check for _mt7530_read, or the arg passed
to it. So pass a struct containing the address and priv.

I think you can then kill of your global lpriv.

[PATCH net-next v3 5/5] net-next: dsa: add dsa support for Mediatek MT7530 switch

2017-03-29 Thread sean.wang

From: Sean Wang 

MT7530 is a 7-ports Gigabit Ethernet Switch that could be found on
Mediatek router platforms such as MT7623A or MT7623N platform which
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
support in the driver, including tag insert for user port distinguishing,
port control, bridge offloading, STP setup and ethtool operation to allow
DSA to model each user port into a standalone netdevice as the other DSA
driver had done.
