network-functions: use tr to upper case strings rather than awk
network-functions uses awk to tranform the mac address to upper case.
Replace awk with tr which is two order of magnitude faster:
$ time awk '{ print toupper($0) }' </usr/share/dict/words >/dev/null
real 0m0,227s
user 0m0,224s
sys 0m0,004s
$ time tr '[a-z]' '[A-Z]' </usr/share/dict/words >/dev/null
real 0m0,005s
user 0m0,000s
sys 0m0,005s
Also use here-strings instead of spawning a subshell and a pipe.
