Subject: [PATCH] wifi: mac80211: add support for letting drivers register tc
offload support
On newer MediaTek SoCs (e.g. MT7986), WLAN->WLAN or WLAN->Ethernet flows can
be offloaded by the SoC. In order to support that, the .ndo_setup_tc op is
needed.

Subject: [PATCH] net: ethernet: mtk_eth_soc: add code for offloading flows
from wlan devices
WED version 2 (on MT7986 and later) can offload flows originating from wireless
devices. In order to make that work, ndo_setup_tc needs to be implemented on
the netdevs. This adds the required code to offload flows coming in from WED,
while keeping track of the incoming wed index used for selecting the correct
PPE device.

Subject: [PATCH] net: ethernet: mediatek: fix ppe flow accounting for L2
flows
For L2 flows, the packet/byte counters should report the sum of the
counters of their subflows, both current and expired.
In order to make this work, change the way that accounting data is tracked.
Reset counters when a flow enters bind. Once it expires (or enters unbind),
store the last counter value in struct mtk_flow_entry.
