[ Upstream commit8a9922e7be] ipvlan_queue_xmit() should return NET_XMIT_XXX, but ipvlan_xmit_mode_l2/l3() returns rx_handler_result_t or NET_RX_XXX in some cases. ipvlan_rcv_frame() will only return RX_HANDLER_CONSUMED in ipvlan_xmit_mode_l2/l3() because 'local' is true. It's equal to NET_XMIT_SUCCESS. But dev_forward_skb() can return NET_RX_SUCCESS or NET_RX_DROP, and returning NET_RX_DROP(NET_XMIT_DROP) will increase both ipvlan and ipvlan->phy_dev drops counter. The skb to forward can be treated as xmitted successfully. This patch makes ipvlan_queue_xmit() return NET_XMIT_SUCCESS for forward skb.
