[PATCH 1/1] staging: hv: Fix missing functions for net_device_ops
From: Haiyang Zhang <haiyangz at microsoft.com> Subject: staging: hv: Fix missing functions for net_device_ops Unlike in older kernels, ether_setup() no longer sets default functions. We need to put them into net_device_ops. For example, eth_change_mtu prevents setting MTU beyond 1500. This is necessary because we don't support jumbo frame at this time.

[PATCH 1/1] staging: hv: Fix missing functions for net_device_ops (with detailed comments)
From: Haiyang Zhang <haiyangz at 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...
