Subject: [PATCH] net: ethernet: mtk-ppe: fix traffic offload with bridged wlan
|
||
|
|
||
|
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.
