Currently veth drops all packets larger then the mtu set on the receiving end of the pair. This is inconsistent with most hardware ethernet drivers.
This patch set adds a new driver attribute to set the maximum size of received packet to make it possible to create configurations similar to those possible with (most) hardware ethernet interfaces. The set consists of two patches. The first one adding a parameter do the dev_forward_skb functions to specify the maximum packet size, the second one implents a new attribute (VETH_MRU) in the veth driver.
