Radix sorting bug affecting IPSec performance.

[Nikolay Denev]

This line from the OpenBSD 4.9 release notes attracted my attention : 
  "A radix tree sorting bug was fixed, which results in significant improvements to IPsec performance under certain conditions.|

And this seems to be the relevant commit : http://www.openbsd.org/cgi-bin/cvsweb/src/sys/net/radix.c?rev=1.28;sortby=date

Looking at the FreeBSD code it seems that is also affected, maybe it's a good idea to add their fix in FreeBSD :)
