2 questions

1. What do you mean when you say we should support operation of clean_rule_table? (in user space)?
should we clear the file of the rules we got? 
2. Can you expain what is the meaning of desable/enable the firewall?
How? 
Should we print error about this?
 
Thanks!

1. As explaind in the lecture, delete the rules you loaded to the module to make the table empty. after this command, the command show_rule_table will return an empty table.
2. if the firewall is disabled, packets shouldn't go through the rule table, just be logged and pass through. how? it's up to you
