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: mtk_ppe: prefer newly added l2
flows over existing ones
When a device is roaming between interfaces and a new flow entry is created,
we should assume that its output device is more up to date than whatever
entry existed already.
