First bottleneck was discovering the max MTU allowed on these is 7K instead of 9K but googling seems to indicate that the RTL8168B is only capable of 4K frames.
Yeah, the 8168C goes up to 7k. Some 8168B go up to 6k.
In cases like this where there are conflicting sources of information regarding the max MTU of a NIC, what would be the correct way to determine the actual max MTU? I figured the 7K limit basically by doing a binary search with the ifconfig mtu commands. But is the this figure simply what the driver will accept for the controller it identified or is that the actual hardware limit?
