Instead of above function you can declare const array of strings as below to 
map hash function names.

static const char * const hf_names[] = {
        [RTE_ETH_HASH_FUNCTION_SIMPLE_XOR] = " simple_xor ",
        [RTE_ETH_HASH_FUNCTION_TOEPLITZ] = " toeplitz ",
        [RTE_ETH_HASH_FUNCTION_SYMMETRIC_TOEPLITZ] = " symmetric_toeplitz ",
        [RTE_ETH_HASH_FUNCTION_DEFAULT] = "default"
};

And then print  as below ?
printf("\t  -- hash algorithm : %s\n", hf_names [rss_conf.func]);
