In the 10 Gigabit Ethernet MAC v13.0 (Rev. 1) and earlier, the oversized frame count could be larger than the frame when using MTU or when jumbo frames are disabled.
- When jumbo frames are disabled in the transmitter and a jumbo frame is transmitted, the TX frame length count (part of the TX_STATISTICS_VECTOR) should stick to either 1518 for non-VLAN frames or 1522 for VLAN frames.
Currently it sticks to 1526.
- If the Maximum Transmission Unit (MTU) is set on the TX side to a valid value, the counter sticks to a value that is always bigger by 8 than the set MTU size.
