Stephen Hemminger c0b8c32b1c IPV4: use xor rather than multiple ands for route compare 
The comparison in ip_route_input is a hot path, by recoding the C
"and" as bit operations, fewer conditional branches get generated
so the code should be faster. Maybe someday Gcc will be smart
enough to do this?
