Also ./odp_classifier -h says

Mandatory OPTIONS:
-i, --interface Eth interface
-p, --policy <odp_pmr_term_e>:<match type>:<value1>:<value2>:<queue name>
Yet I did not pass -p so I assume it is not mandatory ?
This is an issue and I will correct the same in next version. -p is a
mandatory option.

That is not good I think:
void *odp_shm_addr(odp_shm_t shm)
{
uint32_t i;
i = from_handle(shm);
if (i > (ODP_CONFIG_SHM_BLOCKS - 1))
return NULL;
return odp_shm_tbl->block[i].addr;
}
There is might be some block which was not freed it's addr.
You need to check shm == ODP_SHM_INVALID.
Thanks,
Maxim.
