This one is intentional, since struct mtk_wed_device will be empty if CONFIG_NET_MEDIATEK_SOC_WED is not set. The code would not compile without the #ifdef. Thanks, - Felix

After this update ctx.dev might be NULL? Right. I added this check to be able to prevent dev_fill_forward_path from adding an extra DEV_PATH_ETHERNET entry, which is not applicable for wlan devices. - Felix

Can you give me a pseudo-code example? I'm not sure how you want it to be exposed through the flow offload API. To me it seems easier and cleaner to just have a single ndo_fill_forward_path call for the final output device to check the device types that don't have any corresponding sw offload. >> - return dp->index; >> -#else >> - return -ENODEV; >> -#endif >> -} >> - >> -static int >> -mtk_flow_set_output_device(struct mtk_eth *eth, struct mtk_foe_entry *foe, >> - struct net_device *dev) >> -{ >> - int pse_port, dsa_port; >> + switch (path.type) { >> + case DEV_PATH_DSA: > > This DSA update is not related, right? I consider it related. Since I'm calling ndo_fill_forward_path now, it's better to use it for both DSA and WLAN instead of having independent checks. - Felix

I think it should probably be called FLOW_ACTION_MTK_WDMA (and be mediatek specific), or we should pick a more generic name for it. > It's a bit of work the first time to accomodate the requirements of > new API, but then all drivers will benefit from this. > > It's also a bit of layering, but with more drivers in the tree, this > API can be simplified incrementally. > > I can take a stab at it and send you a patch. Thanks. If we do this for WDMA, shouldn't we also do it for DSA to keep things consistent? - Felix
This patch series adds hardware flow offloading for routing/NAT packets from ethernet to WLAN on MT7622 SoC, in combination with MT7915 WLAN devices This only offloads one direction, WLAN->Ethernet offload is not supported by MT7622 (but will be in newer SoC designs). In order to make this work, the SoC contains a subsystem named Wireless Ethernet Dispatch. It intercepts access to the WLAN DMA register space and controls the DMA queues in order to be able to inject packets coming in from the packet processing engine (PPE). It also intercepts IRQs from PCIe.
