From: Woojung Huh <Woojung.Huh@microchip.com>

The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch
with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs.
The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII
or RMII. Either of these may connect directly to a host processor or
to an external PHY. The SGMII port may interface to a fiber optic transceiver.

This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.

Hi Woojung

Do we need cpu_port in this table? Can any port be used as a CPU port?
From the code in ksz_config_cpu_port() it seems like it can.

And do we need enabled_ports? This seems to suggest only ports 0-4 can
be user ports?

Thanks

You should check, but i think devm_kmalloc_array sets the allocated
memory to 0. So i don't think you need the memset. If it is needed, i
would move it here, after the check the allocation is successful.

I wounder if the vlan cache should be protected my a mutex?

Missing timeouts if the hardware stops responding. There are a few
other similar loop i spotted. Please add a timeout for them all. Maybe
add a generic helper function if it makes sense?

Since the mutux has been released, could this empty entry be stolen by
some other parallel running thread? It seems like you should keep hold
of the mutex until you have at least marked it as used.

Here also, i wounder if it is safe the release the mutex and then
later claim it?

Is there a need for this? Is there silicon with the wrong ID in it?

Please leave the compiler to decide if to inline the function. The
same applies everywhere in .c files.

Overall the code is nice, just a few small issues to sort out.

    No. Else there would be no need for it, since kcalloc() is a function that 
allocates the arrays and zeroes them.

    If it could be done here, kcalloc() should be used.

Andrew & Sergei,

Source shows that devm_kcalloc() calls devm_kmalloc_array() wit __GFP_ZERO.
Will use it instead.

Thanks.

Andrew,

Intention of cpu_port is for default cpu_port when devicetree doesn't have it.
However, it won't get back to dst, so it won't be needed.
Will remove it.

Enabled_ports was to configure physically connected ports. (For instance, 7 ports switch but board only uses 4 ports.)
This code path is not working as expected. Will update at next version of patch.

Thanks.

FWIW, the b53 driver has a similar set of constructs (which is probably
where you got this from), and this needs fixing too. cpu_port is a good
indication of which ports can support tags, whereas enabled_ports is
completely redundant with ds->enabled_port_mask.

Once net-next opens again, the plan is to stop using these private
constructs and switch to using what DSA provides.

BTW, there are only a few things that make sense to be represented as a
true number, most attributes of a switch (port number, locations etc.)
are truly bitmasks.
