It's a bug when porting the drivers from 2.6.27 to 2.6.32. In 2.6.27, the default functions for Ethernet, like eth_change_mtu(), were assigned by ether_setup(). But in 2.6.32, these function pointers moved to net_device_ops structure and no longer be assigned in ether_setup(). So we need to set these functions in our driver code. It will ensure the MTU won't be set beyond 1500. Otherwise, this can cause an error on the server side, because the HyperV linux driver doesn't support jumbo frame yet.
