Reproducing CrystalDiskMark tests with fio - fixes for https://unix.stackexchange.com/revisions/480191/9
#!/bin/bash
# This script is based on https://unix.stackexchange.com/revisions/480191/9 .
# The following changes proved to be necessary to make it work on CentOS 7:
# * removed disk info (model, size) - not very useful, might not work in many cases.
# * using "bw" instead of "bw_bytes" to support fio version 3.1 (those availible through yum @base)
# * escaping exclamation mark in sed command
# * the ".fiomark.txt" is not auto-removed

These PMKID values are computed this way:

PMKID = HMAC-SHA1-128(PMK, "PMK Name" | MAC_AP | MAC_STA)
