So, if I want to check the template of a chain, I have to use 'tc chaintemplate... chain X'. If I want to check the filters in a chain, I have to use 'tc filter show .... chain X'. If you introduce 'tc chain', it would just need one command: `tc chain show ... X` which could list its template first and followed by filters in this chain, something like: # tc chain show dev eth0 chain X template: # could be none .... filter1 ... filter2 ... Isn't it more elegant?
