It does not compile with 32-bit toolchain:

drivers/net/softnic/rte_eth_softnic_thread.c:140:28: error:
cast between incompatible function types
from ‘int (*)(uint16_t)’ {aka ‘int (*)(short unsigned int)’}
to ‘int32_t (*)(void *)’ {aka ‘int (*)(void *)’}
  service_params.callback = (rte_service_func)rte_pmd_softnic_run;
                            ^

Fixing in-tree.
