  During initialization of rte_hash_table_ext and rte_hash_table_lru,
t->data_size_shl is calculated.  This member contains the number of
bits to shift left during calculation of the location of entries in
the hash table.  To determine the number of bits to shift left, the
size of the entry (as provided to the rte_table_hash_ext_create and
rte_table_hash_lru_create) has to be used instead of the size of the
key.
