Subject: [PATCH 1/1] staging: hv: Fix missing functions for net_device_ops
 (submit again)

From: Haiyang Zhang <haiyangz@...rosoft.com>

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.
It affects kernel 2.6.32 and later, which are all versions
containing Hyper-V drivers.
