This log shows that you are using Passive FTP

> tc filter add dev eth0 parent 10: protocol ip prio 100 u32 match ip sport
> 20 0xffff flowid 10:10

now you put up a rule for sport 20.
Passiv FTP does not use sport 20, it uses any port > 1024, 
only "active" FTP uses port 20 as sport for data transfare,..
