Subject: [PATCH net-next v4 2/2] net: ethernet: mediatek: modify GDM to send packets to the PDMA for RX
Date: Fri, 26 Aug 2016 01:09:43 +0800 [thread overview]
Message-ID: <1472144983-5048-3-git-send-email-nelson.chang@mediatek.com> (raw)
In-Reply-To: <1472144983-5048-1-git-send-email-nelson.chang@mediatek.com>
Because we change to use the PDMA as the Ethernet RX DMA engine,
the patch modifies to set GDM to send packets to PDMA for RX.
