Subject: [PATCH] net: ethernet: mtk-star-emac: return ok when xmit drops
Date: Thu, 12 Nov 2020 09:48:33 +0100	[thread overview]
Message-ID: <20201112084833.21842-1-vincent.stehle@laposte.net> (raw)

The ndo_start_xmit() method must return NETDEV_TX_OK if the DMA mapping
fails, after freeing the socket buffer.
Fix the mtk_star_netdev_start_xmit() function accordingly.

Fixes: 8c7bd5a454ff ("net: ethernet: mtk-star-emac: new driver")
