Not used anymore, can be removed.

It's not needed, test.sh (which included by test_net.sh) has all checksfor
LTPROOT

Not portable "for (());", could be changed to "for i in $(seq 0 
${#str}); do.

c var is redundant, we can substitute "$c" with "${str:$i:1}"

if [ "$1" = "flush"]; then

I would run each ip commands with ROD "ip ..." and tst_rhost_run with -s 
option.
In that way, if command fails, test will exit with TBROK.
