Change the unit of srtt and rto to usec, inspired by these in struct "tcp_info". Therefore, no need hz and tcp_rtt_scale in the headline of the log. Update the man page as well.
Summary: Simplify srtt and rto values in siftr log.

Test Plan:
Tested in Emulab testbed:

net.inet.siftr.enabled: 0
cc@s1:~ % sudo sysctl net.inet.siftr.port_filter=5001
net.inet.siftr.port_filter: 0 -> 5001
cc@s1:~ % sudo sysctl net.inet.siftr.enabled=1

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
