You cannot simplily delete the code, as rte_gro_timeout_flush()
is designed to flush packets according to cycles. If users
want to flush all packets from the table, they can set
'timeout_cycles' in rte_gro_timeout_flush() to 0.
rte_gro_reassemble_burst() uses this way to return all
packets of a burst to users after GRO.
