Subject: [PATCH v4 net-next 09/13] netfilter: nft_flow_offload: Add DEV_PATH_MTK_WDMA to nft_dev_path_info()
Date: Tue, 7 Jan 2025 10:05:26 +0100 [thread overview]
Message-ID: <20250107090530.5035-10-ericwouds@gmail.com> (raw)
In-Reply-To: <20250107090530.5035-1-ericwouds@gmail.com>
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.
