  The example should use the IPv4 addresses defined in RFC5735 and
the IPv6 addresses defined in RFC5180 for the L3 forwarding example
Longest Prefix Match table.

Fixes: 268888b5b020 ("examples/l3fwd: modularize")

Should the depth value of 48 be used instead of 64 in the lines above?

> +	{{32, 1, 2, 0, 0, 0, 0, 0, 0, 7, 0, 0, 0, 0, 0, 0}, 48, 0},

Should 20 be used instead of 32 in the lines above ?
