net: dsa: qca8k: reduce mgmt ethernet timeout2022-06-23T01:33:51+00:00Christian Marangiansuelsmth@gmail.com2022-06-21T15:16:33+00:00urn:sha1:85467f7da18992311deafdbf32a8d163cb1e98d7
The current mgmt ethernet timeout is set to 100ms. This value is too
big and would slow down any mdio command in case the mgmt ethernet
packet have some problems on the receiving part.
Reduce it to just 5ms to handle case when some operation are done on the
master port that would cause the mgmt ethernet to not work temporarily.

Now that dsa_switch_ops is not switch specific anymore, we can drop it
from qca8k_priv and use the static ops directly for the dsa_switch
pointer.

net: dsa: qca8k: rework and simplify mdiobus logic2022-04-17T12:28:28+00:00Ansuel Smithansuelsmth@gmail.com2022-04-15T23:30:14+00:00urn:sha1:8255212e4130bd2dc1463286a3dddb74797bbdc1
In an attempt to reduce qca8k_priv space, rework and simplify mdiobus
logic.
We now declare a mdiobus instead of relying on DSA phy_read/write even
if a mdio node is not present. This is all to make the qca8k ops static
and not switch specific. With a legacy implementation where port doesn't
have a phy map declared in the dts with a mdio node, we declare a
'qca8k-legacy' mdiobus. The conversion logic is used as legacy read and
write ops are used instead of the internal one.
Also drop the legacy_phy_port_mapping as we now declare mdiobus with ops
that already address the workaround.

net: dsa: qca8k: drop port_sts from qca8k_priv2022-04-17T12:28:28+00:00Ansuel Smithansuelsmth@gmail.com2022-04-15T23:30:13+00:00urn:sha1:2b8fd87af7f156942971789abac8ee2bb60c03bc
Port_sts is a thing of the past for this driver. It was something
present on the initial implementation of this driver and parts of the
original struct were dropped over time. Using an array of int to store if
a port is enabled or not to handle PM operation seems overkill. Switch
and use a simple u8 to store the port status where each bit correspond
to a port. (bit is set port is enabled, bit is not set, port is disabled)
Also add some comments to better describe why we need to track port
status.

net: dsa: qca8k: drop MTU tracking from qca8k_priv2022-04-17T12:28:28+00:00Ansuel Smithansuelsmth@gmail.com2022-04-15T23:30:12+00:00urn:sha1:69fd055957a02309ffdc23d887a01988b6e5bab1
DSA set the CPU port based on the largest MTU of all the slave ports.
Based on this we can drop the MTU array from qca8k_priv and set the
port_change_mtu logic on DSA changing MTU of the CPU port as the switch
have a global MTU settingfor each port.

From Documentation, we can cache lo and hi the same way we do with the
page. This massively reduce the mdio write as 3/4 of the time as we only
require to write the lo or hi part for a mdio write.

Use mgmt Ethernet also for phy read/write if availabale. Use a different
seq number to make sure we receive the correct packet.
On any error, we fallback to the legacy mdio read/write.
