Jorge - i guess your traffic is locally generated (on same PC where is shaper, 
this traffic generated), thats why shaping was not precise, with enabled 
GSO/TSO. I am right?

My conclusion based on:
eth0      Link encap:Ethernet  HWaddr 00:13:d4:68:c6:33
          inet addr:195.23.114.76  Bcast:195.23.114.79  Mask:255.255.255.248

and
/sbin/tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip
src 195.23.114.76 match ip sport 80 0xffff classid 1
:1280



My traffic is "transit", means just passing router. I guess if it is correct, 
there must be statement about difference in locally generated traffic and 
transit traffic. TSO/GSO offloading i guess not done for "passing thru" 
traffic.
