CVS commit: [jdolecek-ncq] src/sys/dev/ata

Module Name:    src
Committed By:   jdolecek
Date:           Thu Sep 28 20:34:23 UTC 2017

Modified Files:
        src/sys/dev/ata [jdolecek-ncq]: TODO.ncq wd.c wdvar.h

Log Message:
add sysctls to control if NCQ is being used, and how many max tags;
I have a drive which is significantly slower with NCQ than non-NCQ,
and it's generally useful to have this easily overridable

while here, also move the frequency settings for WD_CHAOS_MONKEY
to a sysctl and make it per-drive
