* net: ethernet: mtk-ppe: fix traffic offload with bridged wlanLorenzo Bianconi2022-07-251-17/+13
| | | | | | | | | | | | | A typical flow offload scenario for OpenWrt users is routed traffic received by the wan interface that is redirected to a wlan device belonging to the lan bridge. Current implementation fails to fill wdma offload info in mtk_flow_get_wdma_info() since odev device is the local bridge. Fix the issue running dev_fill_forward_path routine in mtk_flow_get_wdma_info in order to identify the wlan device.
