The Ethter_type of Mac_learning Ethternet frame in mode TLB/ALB is set to 0x0060(ETH_P_LOOP),which is not a valid ether_type. Results in this frame is interpreted as a 802.3 LLC message who's length word not matches the actual length by the Hub.The aim to let the hub to learning the Mac can be done correctly.
But something confuse me a little .

quote from site above:
These packets are not invalid, they are merely using the very old DIX protocol type 0x0060 which is the Ethernet Loopback protocol, used for link testing.Any messages and counters caused by these frames may be safely ignored.
But，i really can't find it in A site can't be post here(Sorry, you were not able to save since the content contained a link).
2、Since Hub will counter it as an abnormal frames , why we don't change it .
3、i am wrong?
Is there someone know something about it?
