the register bits for TX delay and RX delay are opposites:
when TX delay bit is set, delay is enabled
when RX delay bit is set, delay is disabled
So, when both bits are unset, it is RX delay
and when both bits are set, it is TX delay
Note: TXID is the default RGMII mode of the SOC

The function mt7620_mdio_mode is only called once
and both the function and mdio_mode block have been named incorrectly,
leading to confusion and useless commits.
These lines in the mdio_mode block of mt7620_hw_init
are only intended for boards with an external mt7530 switch.
(see commit 194ca6127e)
Therefore, move lines from mdio_mode to the place in soc_mt7620.c
where the type of mt7530 switch is identified,
and move lines from mt7620_mdio_mode to a main function.
mt7620_mdio_mode was called from mt7620_gsw_init
where the priv struct is available,
so the lines must stay in mt7620_gsw_init function.
In order to keep things as simple as possible,
keep the DTS property related function calls together,
by moving them from mt7620_gsw_probe to init.
Remove the now useless DTS properties and extra phy nodes.

Set the PHY base address to 12 for mt7530 and 8 for others,
which is based on the default setting for some devices
from printing the register with the following command
after it is written to by uboot during the boot cycle.
`md 0x10117014 1`
PHY_BASE option only uses 5 bits of the register,
bits 16 to 20, so use 8-bit integer type.
Set the option using the DTS property mediatek,ephy-base
and create the gsw node if missing.
Also, added a kernel message to display the EPHY base address.
Note:
If anything is written to a PHY address that is greater than 1 hex char (greater than 0xf)

When the new variable ephy_base was introduced,
it was not applied to the if block for mdio_mode.
The first line in the mdio_mode if block
sets the EPHY base address to 12 in the SOC by writing a register,
but the corresponding variable in the driver
was still set to the default of 0.
This causes subsequent lines that write registers with the function
_mt7620_mii_write
to write to PHY addresses 0 through 4
while internal PHYs have been moved to addresses 12 through 16.
All of these lines are intended only for PHYs on the SOC internal switch,
however, they are being written to external ethernet switches
if they exist at those PHY addresses 0 through 4.
This causes some ethernet ports to be broken on boards with AR8327 or QCA8337 switch.
Other suggested fixes move those lines to the else block of mdio_mode,
but removing the else block completely also fixes it.
Therefore, move the lines to the mt7620_hw_init function main block,
and have only one instance of the function mtk_switch_w32
for writing the register with the EPHY base address.
In theory, this also allows for boards that have both external switches
and internal PHYs that lead to ethernet ports to be supported.

A workaround was added to the switch driver
to set SOC port 4 as an RGMII GMAC interface
based on the DTS property mediatek,port4-gmac.
(previously mediatek,port4)
However, the ethernet driver already does this,
but is being blocked by a return statement
whenever the phy-handle and fixed-link properties
are both missing from nodes that define the port properties.
Revert the workaround, so that both the switch driver
and ethernet driver are not doing the same thing
and move the phy-handle related lines down
so nothing is ending the function prematurely.
While at it, clean up kernel messages

These nodes are used for configuring a GMAC interface
and for defining external PHYs to be accessed with MDIO.
None of this is possible on MT7620N, only MT7620A,

When the mdio-bus node is missing, the driver returns -NODEV

The mt7530_{r,w}32 operation over MDIO uses 3 mdiobus operations and

While commit 734a8c46e7 focussed on removing stuff directly

The mt7621 subtarget has been switched to DSA quite a while ago and
seems to run sufficiently fine. Build with older kernels than 5.4 has
been disabled directly during the kernel bump, so our local ethernet
driver is unused in master since then.
Therefore, let's remove the mt7621-specific parts of "our" ethernet
driver, so we don't have to maintain them and it's obvious to
everybody that they are not used anymore.
This also drops the offloading components as this was specifically
implemented to depend on mt7621.

The default switch frame size (with FCS + header) is 1536 bytes. But the

VLAN header added by the switch.

The driver assumes that the maximum received buffer for non-jumbo frames is
1536 bytes. But the allocation of the rx fragment doesn't reflect that. It
currently allocates fragments which will only be large enough to be used as
rx buffer with the size of 1534 bytes. This is problematic because the GMAC
will now try to write to 2 bytes which don't belong to its receive buffer
when a large enough ethernet frame is received.
This may already be a problem on existing chips but will at least become a
problem when the 1536 byte rx modus is enabled on MT7621a. It is required
on this SoC to receive ethernet frames which use their full 1500 bytes MTU
and a VLAN header next to the switch VLAN tag.

The length of the DMA rx buffer was always set to 0 because the function

Instead the macro has to be split in a get and set function similar to the

The MT7530 switch driver with enable_vlan set will automatically set all
ports to the user port mode. The hardware will remove the incoming vlan tag
on these ports and use it for its internal vlan. This is usually not wanted
and makes it impossible to communicate via vlan over the switch in both
directions.
It is possible to configure a switch port to "transparent mode" when this
port is only used as untag in the switch VLANs. This will disable the VLAN
untagging of packets when they were received on this port. The tagging on
"tag" ports based on the vlan id is still working.
The transparent port mode cannot be used when a port is both used in a VLAN
as "tag" and in another one as "untag" port.

Use doubletagging to disable ramips_esw vlan by default, it seems
more reliable.
Daniel Golle found an issue where sometimes (possibly only for
RT3352) the default vlan disable method (clearing en_vlan, untag,
doubletag and putting all ports into vlan 0) doesn't work and the
packets get sent out vlan-tagged with vlan 0.
Instead switch to using the doubletagging method (allow doubletagged
packets, put all ports into vlan 0 with untag enabled) by default.
Unless someone figures out a way to really globally disable vlan for
this switch, this seems like the best (most reliable) option.
I did some tests regarding maximum packet size and did not see any
difference between the two methods, both allow for slightly bigger packets
than the ramips_main.c ethernet driver (ping stops going through
above "ping -s 1472" (1514 bytes), on the switch packets are recv_good until
"ping -s 1490", or about 1532 bytes).
