I want to reverse a the following:
00:11:22:33:44:55

I currently use something like below to pass it as is.
But now I want the same script to reverse the above and pass it to ethtool.

// psuedo code

i=0
skip=0
for m in $@
do
if [ $skip -eq 0 ]
then
skip=1
for b in $(echo $m | tr ':' ' ')
do
ethtool -E eth$i offset $c value 0x$b
c=$(($c + 1))
done
else
skip=0
fi
i=$(($i + 1))
done
echo "OK"


Thank you
