10267e1729 ramips: 5.10: port and refresh patches, ralink drv
Enable testing kernel.

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.

Run automatic quilt refresh on the rest.

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.
