Within our design, we have some hash tables with 4= -byte keys. While going through the changes done in 17.11, we have found th= ere was an added key_size check, which now requires key_size >=3D 8 bytes (= see check_params_create() in rte_table_hash_ext.c). Not seeing any other op= tions, so I was hoping someone could advise on how to support a 4-byte hash= key size in 17.11 and on a go forward basis. Regards, Mike
