The current implementation is based on the FreeBSD and Linux.
All counters I added to NetBSD are also counted on both FreeBSD
and Linux. There are some difference between those two.
I also noticed that some code are doubtful and wrote them the
different way. To make the implementation perfect, I have to
read (almost) all datasheets and test on some chips. It's not
good to write only based on the datasheets. One of the reason is
that, for example, a register is not listed in the statistics
counters' table but the detail of the register is described later
in the chapter. It's not clear whether the register is exist
or not. The current implementation may not count some useful
counters.
The current implementation is not the final form but it's worth
to have. I could have written the details of the current
implementation when I committed, but I didn't really feel the
need to write the details of the implementation in its half-way
state. My apologies.
Thanks.
