mt7530_pad_clk_setup() is called if port 6 is enabled. It used to do more
things than setting up port 6. That part was moved to more appropriate
locations, mt7530_setup() and mt7530_pll_setup().
Now that all it does is set up port 6, rename it to mt7530_setup_port6(),
and move it to a more appropriate location, under mt7530_mac_config().
Change mt7530_setup_port6() to void as there're no error cases.
Leave an empty mt7530_pad_clk_setup() to satisfy the pad_setup function
pointer.
This is the code path for setting up the ports before:
dsa_switch_ops :: phylink_mac_config() -> mt753x_phylink_mac_config()
-> mt753x_mac_config()
-> mt753x_info :: mac_port_config() -> mt7530_mac_config()
-> mt7530_setup_port5()
-> mt753x_pad_setup()
-> mt753x_info :: pad_setup() -> mt7530_pad_clk_setup()
This is after:
dsa_switch_ops :: phylink_mac_config() -> mt753x_phylink_mac_config()
-> mt753x_mac_config()
-> mt753x_info :: mac_port_config() -> mt7530_mac_config()
-> mt7530_setup_port5()
-> mt7530_setup_port6()

This code is from before this driver was converted to phylink API. Phylink
deals with the unsupported interface cases before mt7530_pad_clk_setup() is
run. Therefore, the default case would never run. However, it must be
defined nonetheless to handle all the remaining enumeration values, the
phy-modes.
Switch to if statement for RGMII and return which simplifies the code and
saves an indent.
Set P6_INTF_MODE, which is the three least significant bits of the
MT7530_P6ECR register, to 0 for RGMII even though it will already be 0
after reset. This is to keep supporting dynamic reconfiguration of the port
in the case the interface changes from TRGMII to RGMII.
Disable the TRGMII clocks for all cases. They will be enabled if TRGMII is
being used.
Read XTAL after checking for RGMII as it's only needed for the TRGMII
interface mode.

Use slowwait instead of hard code sleep for bonding tests.
In function setup_prepare(), the client_create() will be called after
server_create(). So I think there is no need to sleep in server_create()
and remove it.
For lab_lib.sh, remove bonding module may affect other running bonding tests.
And some test env may buildin bond which can't be removed. The bonding

The purpose of grat_arp is testing commit 9949e2efb5 ("bonding: fix
send_peer_notif overflow"). As the send_peer_notif was defined to u8,
to overflow it, we need to
send_peer_notif = num_peer_notif * peer_notif_delay = num_grat_arp * peer_notify_delay / miimon > 255
(kernel) (kernel parameter) (user parameter)
e.g. 30 (num_grat_arp) * 1000 (peer_notify_delay) / 100 (miimon) > 255.
Which need 30s to complete sending garp messages. To save the testing time,
the only way is reduce the miimon number. Something like
30 (num_grat_arp) * 100 (peer_notify_delay) / 10 (miimon) > 255.
To save more time, the 50 num_grat_arp testing could be removed.
The arp_validate_test also need to check the mii_status, which sleep
too long. Use slowwait to save some time.
For other connection checkings, make sure active slave changed first.

net: Unify C22 and C45 error handling during bus enumeration
When enumerating an MDIO bus, an MDIO bus driver can return -ENODEV to
a C22 read transaction to indicate there is no device at that address
on the bus. Enumeration will then continue with the next address on
the bus.
Modify C45 enumeration so that it also accepts -ENODEV and moves to
the next address on the bus, rather than consider -ENODEV as a fatal
error.
Convert the mv88e6xxx driver to return -ENODEV rather than 0xffff on
read for families which do not support C45 bus transactions. This is
more efficient, since enumeration will scan multiple devices at one
address when 0xffff is returned, where as -EONDEV immediately jumps to
the next address on the bus.

MDIO bus drivers can return -ENODEV when they know the bus does not
have a device at the given address, e.g. because of hardware
limitation. One such limitation is that the bus does not support C45
at all. This is more efficient than returning 0xffff, since it
immediately stops the probing on the given address, where as further
reads can be made when 0xffff is returned.

When scanning the MDIO bus for C22 devices, the driver returning
-ENODEV is not considered fatal, it just indicates the MDIO bus master
knows there is no device at that address, maybe because of hardware
limitation.
Make the C45 scan code act on -ENODEV the same way, to make C22 and
C45 more uniform.
It is expected all reads for a given address will return -ENODEV, so
within get_phy_c45_ids() only the first place a read occurs has been
changed.
