Export the symbols to fix the below errors when built as modules:
ERROR: "tso_build_data" [drivers/net/ethernet/marvell/mvneta.ko] undefined!
ERROR: "tso_build_hdr" [drivers/net/ethernet/marvell/mvneta.ko] undefined!
ERROR: "tso_start" [drivers/net/ethernet/marvell/mvneta.ko] undefined!
ERROR: "tso_count_descs" [drivers/net/ethernet/marvell/mvneta.ko] undefined!
ERROR: "tso_build_data" [drivers/net/ethernet/marvell/mv643xx_eth.ko] undefined!
ERROR: "tso_build_hdr" [drivers/net/ethernet/marvell/mv643xx_eth.ko] undefined!
ERROR: "tso_start" [drivers/net/ethernet/marvell/mv643xx_eth.ko] undefined!
ERROR: "tso_count_descs" [drivers/net/ethernet/marvell/mv643xx_eth.ko] undefined!
