a869d3a5eb net: airoha: Initialize PPE UPDMEM source-mac table
UPDMEM source-mac table is a key-value map used to store devices mac
addresses according to the port identifier. UPDMEM source mac table is
used during IPv6 traffic hw acceleration since PPE entries, for space
constraints, do not contain the full source mac address but just the
identifier in the UPDMEM source-mac table.
Configure UPDMEM source-mac table with device mac addresses and set
the source-mac ID field for PPE IPv6 entries in order to select the
proper device mac address as source mac for L3 IPv6 hw accelerated traffic.

f252493e18 net: airoha: Enable multiple IRQ lines support in airoha_eth driver.
EN7581 ethernet SoC supports 4 programmable IRQ lines for Tx and Rx
interrupts. Enable multiple IRQ lines support. Map Rx/Tx queues to the
available IRQ lines using the default scheme used in the vendor SDK:

- IRQ0: rx queues [0-4],[7-9],15
- IRQ1: rx queues [21-30]
- IRQ2: rx queues 5
- IRQ3: rx queues 6

Tx queues interrupts are managed by IRQ0.

9439db26d3 net: airoha: Introduce airoha_irq_bank struct
EN7581 ethernet SoC supports 4 programmable IRQ lines each one composed
by 4 IRQ configuration registers. Add airoha_irq_bank struct as a
container for independent IRQ lines info (e.g. IRQ number, enabled source
interrupts, ecc). This is a preliminary patch to support multiple IRQ lines
in airoha_eth driver.

df8398fb7b net: airoha: Add matchall filter offload support
Introduce tc matchall filter offload support in airoha_eth driver.
Matchall hw filter is used to implement hw rate policing via tc action
police:

$tc qdisc add dev eth0 handle ffff: ingress
$tc filter add dev eth0 parent ffff: matchall action police \
 rate 100mbit burst 1000k drop

The current implementation supports just drop/accept as exceed/notexceed
actions. Moreover, rate and burst are the only supported configuration
parameters.

00a7678310 net: airoha: Introduce flowtable offload support
Introduce netfilter flowtable integration in order to allow airoha_eth
driver to offload 5-tuple flower rules learned by the PPE module if the
user accelerates them using a nft configuration similar to the one reported
below:

table inet filter {
	flowtable ft {
		hook ingress priority filter
		devices = { lan1, lan2, lan3, lan4, eth1 }
		flags offload;
	}
	chain forward {
		type filter hook forward priority filter; policy accept;
		meta l4proto { tcp, udp } flow add @ft
	}
}

af3cf757d5 net: airoha: Move DSA tag in DMA descriptor
Packet Processor Engine (PPE) module reads DSA tags from the DMA descriptor
and requires untagged DSA packets to properly parse them. Move DSA tag
in the DMA descriptor on TX side and read DSA tag from DMA descriptor
on RX side. In order to avoid skb reallocation, store tag in skb_dst on
RX side.
This is a preliminary patch to enable netfilter flowtable hw offloading
on EN7581 SoC.
