Because DEV_PATH_MTK_WDMA is unknown inside nft_dev_path_info() it returns with info.indev = NULL. Then nft_dev_forward_path() returns without setting the direct transmit parameters. This results in a neighbor transmit, and direct transmit not possible. But we want to use it for flow between bridged interfaces. So this patch adds DEV_PATH_MTK_WDMA to nft_dev_path_info() and makes direct transmission possible.
