From: GUO Zihua <guozihua@xxxxxxxxxx> [ Upstream commit c8ef3c94bda0e21123202d057d4a299698fa0ed9 ] Since Linux now supports CFI, it will be a good idea to fix mismatched return type for implementation of hooks. Otherwise this might get cought out by CFI and cause a panic. ltq_etop_tx() would return either NETDEV_TX_BUSY or NETDEV_TX_OK, so change the return type to netdev_tx_t directly.
