Problem Description:
I've always used TC for my QoS configuration, and always used a 100Mbit Realtek
8139 card.
Now i changed my Switch to a 1000Mbit one, and started using the onboard
Marvell NIC, with "sky2" driver, since then, the QoS just stoped working, and
all my shaping rules, started to shape the traffic to 1/2 KB.


Steps to reproduce:
Below my TC rules, and i've always used and worked when i had the 100Mbit card.
I must remember, if i reinsert the 100Mbit card, the shaping works as expected.
