The PPE enforces output frame size limits via per-tag-layer VLAN_MTU
registers that the driver never initializes. The hardware defaults do
not account for PPPoE overhead, causing the PPE to punt encapsulated
frames back to the CPU instead of forwarding them.
Initialize the registers at PPE start and on MTU changes using the
maximum GMAC MTU. This is a conservative approximation -- the actual
per-PPE requirement depends on egress path, but using the global
maximum ensures the limits are never too small.

If the gmac0 is disabled, the precheck for a valid ingress device will
cause a NULL pointer deref and crash the system. This happens because
eth->netdev[0] will be NULL but the code will directly try to access
netdev_ops.
Instead of just checking for the first net_device, it must be checked if
any of the mtk_eth net_devices is matching the netdev_ops of the ingress
device.

The MT7628 has a fixed-link PHY and does not expose MAC control
registers. Writes to these registers only corrupt the ESW VLAN
configuration.
This patch explicitly registers no-op phylink_mac_ops for MT7628, as
after removing the invalid register accesses, the existing
phylink_mac_ops effectively become no-ops.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning

The Mediatek LynxI PCS is used from the MT7530 DSA driver (where it does
not have an OF presence) and from mtk_eth_soc, where it does
(Documentation/devicetree/bindings/net/pcs/mediatek,sgmiisys.yaml
informs of a combined clock provider + SGMII PCS "SGMIISYS" syscon
block).
Currently, mtk_eth_soc parses the SGMIISYS OF node for the
"mediatek,pnswap" property and sets a bit in the "flags" argument of
mtk_pcs_lynxi_create() if set.
I'd like to deprecate "mediatek,pnswap" in favour of a property which
takes the current phy-mode into consideration. But this is only known at
mtk_pcs_lynxi_config() time, and not known at mtk_pcs_lynxi_create(),
when the SGMIISYS OF node is parsed.
To achieve that, we must pass the OF node of the PCS, if it exists, to
mtk_pcs_lynxi_create(), and let the PCS take a reference on it and
handle property parsing whenever it wants.
Use the fwnode API which is more general than OF (in case we ever need
to describe the PCS using some other format). This API should be NULL
tolerant, so add no particular tests for the mt7530 case.

Use the newly added of_reserved_mem_region_to_resource{_byname}()
functions to handle "memory-region" properties.
The error handling is a bit different for mtk_wed_mcu_load_firmware().
A failed match of the "memory-region-names" would skip the entry, but
then other errors in the lookup and retrieval of the address would not
skip the entry. However, that distinction is not really important.
Either the region is available and usable or it is not. So now, errors
from of_reserved_mem_region_to_resource() are ignored so the region is
simply skipped.

With commit 51a4df60db ("net: ethernet: mtk_eth_soc: convert caps in
mtk_soc_data struct to u64") the capabilities bitfield was converted to
a 64-bit value, but a cap_bit in struct mtk_eth_muxc which is used to
store a full bitfield (rather than the bit number, as the name would
suggest) still holds only a 32-bit value.
Change the type of cap_bit to u64 in order to avoid truncating the
bitfield which results in path selection to not work with capabilities
above the 32-bit limit.
The values currently stored in the cap_bit field are
MTK_ETH_MUX_GDM1_TO_GMAC1_ESW:
BIT_ULL(18) | BIT_ULL(5)
MTK_ETH_MUX_GMAC2_GMAC0_TO_GEPHY:
BIT_ULL(19) | BIT_ULL(5) | BIT_ULL(6)
MTK_ETH_MUX_U3_GMAC2_TO_QPHY:
BIT_ULL(20) | BIT_ULL(5) | BIT_ULL(6)
MTK_ETH_MUX_GMAC1_GMAC2_TO_SGMII_RGMII:
BIT_ULL(20) | BIT_ULL(5) | BIT_ULL(7)
MTK_ETH_MUX_GMAC12_TO_GEPHY_SGMII:
BIT_ULL(21) | BIT_ULL(5)
While all those values are currently still within 32-bit boundaries,
the addition of new capabilities of MT7988 as well as future SoC's
like MT7987 will exceed them. Also, the use of a 32-bit 'int' type to
store the result of a BIT_ULL(...) is misleading.

Set metadata size building the skb from xdp_buff in mediatek driver.
mtk_eth_soc driver sets xdp headroom to XDP_PACKET_HEADROOM so the
headroom is large enough to contain xdp_frame and xdp metadata.
Please note this patch is just compiled tested.

The airoha_eth driver has no codebase shared with mtk_eth_soc one.
Moreover, the upcoming features (flowtable hw offloading, PCS, ..) will
not reuse any code from MediaTek driver. Move the Airoha driver in a
dedicated folder.

mtk_foe_entry_set_vlan() in mtk_ppe.c already supports double vlan
tagging, but mtk_flow_offload_replace() in mtk_ppe_offload.c only allows
for 1 vlan tag, optionally in combination with pppoe and dsa tags.
However, mtk_foe_entry_set_vlan() only allows for setting the vlan id.
The protocol cannot be set, it is always ETH_P_8021Q, for inner and outer
tag. This patch adds QinQ support to mtk_flow_offload_replace(), only in
the case that both inner and outer tags are ETH_P_8021Q.
Only PPPoE-in-Q (as before) and Q-in-Q are allowed. A combination
of PPPoE and Q-in-Q is not allowed.

Add EEE support to MediaTek SoC Ethernet. The register fields are
similar to the ones in MT7531, except that the LPI threshold is in
milliseconds.
