The OpenBSD algorithm has a few flaws; see Amit's paper for more information. For a description of how this algorithm works, please see the comments within the code. Note that this commit does not yet enable random IP ID generation by default. There are still some concerns that doing so will adversely affect performance. Reviewed by: rwatson MFC After: 2 weeks END
