[PATCH RFC v1 net-next 10/12] netfilter: nft_flow_offload: Add DEV_PATH_MTK_WDMA to nft_dev_path_info()

[Eric Woudstra]

In case of using mediatek wireless, in nft_dev_fill_forward_path(), the
forward path is filled, ending with mediatek wlan1.

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.
