ramips: add support for kernel 5.10
Enable testing kernel.

Delete upstreamed patches:
 0098-disable_cm.patch can be dropped, upstream fixed CM handling.

Fix compile errors by using new kernel APIs.

Fix fuzz by manually editing patches to ensure the code goes in the
right place.

For 721-NET-no-auto-carrier-off-support.patch, revert upstream commit
a307593a6 to keep the OpenWrt ralink driver operational.

Add mt7621-pci-phy patch to select REGMAP_MMIO as discussed in PR #3693
and #3952.

Rename patches to follow the 3-digit classification from the OpenWrt
Developer Guide.

Run automatic quilt refresh.

adf830a3a5 ramips: remove further mt7621 code from local ethernet driver
While commit 734a8c46e7 focussed on removing stuff directly
selected by the NET_RALINK_* symbols, this patch removes additional
unused mt7621-specific code from the ethernet driver.

As with the previous patch, the main reason is to reduce the amount
of code we have to maintain and care about.

Note that this patch still keeps a few lines with
IS_ENABLED(CONFIG_SOC_MT7621) in mtk_eth_soc.h/.c, as this file is
still selected for the mt7621 subtarget.

734a8c46e7 ramips: remove legacy ethernet driver components for mt7621
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.

aecac14cc4 ramips: Enable rx of 1536 bytes ethernet frames on MT7621
The default switch frame size (with FCS + header) is 1536 bytes. But the
GMAC only accepted frames up to 1522 bytes. Setting it to 1536 allows to
receive ethernet frames using the full of MTU 1500 + an extra VLAN header +
VLAN header added by the switch.

7b306e3eb3 ramips: Fix too small rx buffer
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.

6b4985b105 ramips: Fix setting of rx buffer length
The length of the DMA rx buffer was always set to 0 because the function
for extracting the length was used to calculate the value for setting it.
Instead the macro has to be split in a get and set function similar to the
TX_DMA_(GET_|)PLEN(0|1) macro.

No problem was noticed on MT7621a before this was changed and thus maybe it
was hidden by different problem which is not yet fixed.

1aab21df9f ramips: Allow to receive vlan over untag ports on MT7530
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.

ced0cf3a94 move ethernet hw init to init/uninit functions
This should fix the stalled irq problem seen by several people.
This is not the real fix, but rather moves the bug to the un/init patch of the driver.
The real bug still needs to be fixed, but this workaround should be suffcient to make
the ethernet stable.

d8b2fef763 ramips: Add missing andmask to ramips_esw register read for recv_good value.
Add missing andmask to ramips_esw register read for recv_good value.

Without the mask, recv_bad leaks into the recv_good packet count.
Didn't notice the bug before since you don't usually get bad
packets, so I only saw it when I was playing with overlength packets
earlier...

04c6143ca9 ramips: Use doubletagging to disable ramips_esw vlan by default, it seems more reliable.
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).

bb0785880a ramips: Rename POC registers
Rename POC registers.

The current code uses POC1-POC3.

The datasheet uses:
POC1: Port Control 0
POC1: Port Control 1
POC2: Port Control 2

So the first POC1 is a typo that should have been POC0, rename the
registers to POC0-POC2 accordingly.

f1b9d77912 ramips: Minor ramips_esw.c cleanup
Stop handling VLAN setup in the kernel.
Removes the obsolete RT305X_ESW_VLAN_CONFIG_BYPASS option I added for
WL-351 and add some extra comments.
Also removes the en_vlan per-port flag that isn't very useful really, it now
is only controlled by the global enable_vlan flag.

3b17f1deb8 ramips: Add swconfig support to ramips_esw.c
Add swconfig support to ramips_esw.c

This patch adds swconfig support for ramips_esw:

Tested on both D-LINK DIR-300 B1 and Sitecom WL-351 (external
rtl8366rb on internal port 5).
I've made sure that in the enable_vlan=0 case it behaves like a dumb
switch, so external switches should work fine with vlans and
verified this on the WL-351.

The current state shown by swconfig is always read directly from HW
registers, new settings only show after 'swconfig dev rt305x set apply'.

1525620b0e ramips: watchdog: use maximum possible timeout by default
As the userspace has no means to determine the maximum possible timeout, use
that as the default and let the userspace lower it when necessary.

As the result the usual OpenWrt install (with busybox's watchdog trying to set
the timeout to 60s on start) is using a 33s timeout on an RT3052 clocked at
384MHz instead of the current 20s default.
