From: Haiyang Zhang on 3 Aug 2010 15:20 From: Haiyang Zhang <haiyangz(a)microsoft.com> Fix missing functions for net_device_ops. It's a bug when porting Linux IC 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. Requesting it to be backported to kernel 2.6.32 and later, which are all versions containing Hyper-V drivers.
