+Subject: [PATCH] net: ethernet: mtk_eth_soc: add support for coherent
+ DMA
+
+It improves performance by eliminating the need for a cache flush on rx and tx
+In preparation for supporting WED (Wireless Ethernet Dispatch), also add a
+function for disabling coherent DMA at runtime.

+Subject: [PATCH] net: ethernet: mtk_eth_soc: add support for Wireless
+ Ethernet Dispatch (WED)
+
+The Wireless Ethernet Dispatch subsystem on the MT7622 SoC can be
+configured to intercept and handle access to the DMA queues and
+PCIe interrupts for a MT7615/MT7915 wireless card.
+It can manage the internal WDMA (Wireless DMA) controller, which allows
+ethernet packets to be passed from the packet switch engine (PSE) to the
+wireless card, bypassing the CPU entirely.
+This can be used to implement hardware flow offloading from ethernet to
+WLAN.

+ support
+
+Add the missing IPv6 flow offloading support for routing only.
+Hardware flow offloading is done by the packet processing engine (PPE)
+of the Ethernet MAC and as it doesn't support mangling of IPv6 packets,
+IPv6 NAT cannot be supported.

+Subject: [PATCH] net: ethernet: mtk_eth_soc: rework hardware flow table
+ management
+
+The hardware was designed to handle flow detection and creation of flow entries
+by itself, relying on the software primarily for filling in egress routing
+information.
+When there is a hash collision between multiple flows, this allows the hardware
+to maintain the entry for the most active flow.
+Additionally, the hardware only keeps offloading active for entries with at
+least 30 packets per second.
+
+With this rework, the code no longer creates a hardware entries directly.
+Instead, the hardware entry is only created when the PPE reports a matching
+unbound flow with the minimum target rate.
+In order to reduce CPU overhead, looking for flows belonging to a hash entry
+is rate limited to once every 100ms.
+
+This rework is also used as preparation for emulating bridge offload by
+managing L4 offload entries on demand.

+Subject: [PATCH] net: ethernet: mtk_eth_soc: support creating mac
+ address based offload entries
+
+This will be used to implement a limited form of bridge offloading.
+Since the hardware does not support flow table entries with just source
+and destination MAC address, the driver has to emulate it.
+
+The hardware automatically creates entries entries for incoming flows, even
+when they are bridged instead of routed, and reports when packets for these
+flows have reached the minimum PPS rate for offloading.
+
+After this happens, we look up the L2 flow offload entry based on the MAC
+header and fill in the output routing information in the flow table.
+The dynamically created per-flow entries are automatically removed when
+either the hardware flowtable entry expires, is replaced, or if the offload
+rule they belong to is removed
