[ Upstream commit 12f7bd252221d4f9e000e20530e50129241e3a67 ]
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.
bcm4908_enet_start_xmit() would return either NETDEV_TX_BUSY or NETDEV_TX_OK, so change the return type to netdev_tx_t directly.
