Eric Dumazet 08361aa807 netfilter: ip_tables: unfold two critical loops in ip_packet_match() 
While doing oprofile tests I noticed two loops are not properly unrolled by gcc

Using a hand coded unrolled loop provides nice speedup : ipt_do_table
credited of 2.52 % of cpu instead of 3.29 % in tbench.
