`iwconfig` and `ethtool` should go in udev(7) rules; that way they
will be applied as soon as the hardware appears -- even if, for some
reason, it happens twice.


The same applies to SATA and PCI settings under /sys:


Anything that is written to /sys/module/*/parameters goes to
modprobe.d(5) -- again, to be applied when the module is inserted, not
at some fixed point:


Use sysctl.conf(5) for settings under /proc/sys:


(Side note: Is it really better to turn the NMI watchdog off?)
