Description of problem:
the value of "init.ConnetctionRate(Mb)" cannot be set to 1G with command "netsh netkvm setparam 0 ConnectRate 1000",but can be set to 1G correctly with command "netsh netkvm setparam 0 ConnectRate 1001",seems there is a little mistake.

Version-Release number of selected component (if applicable):
virtio-win-prewhql-65
kernel-2.6.32-393.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.377.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.boot a win2012 guest with virtio-net-pci
2.Registration in NetSH (instllation):
   1).cmd --> run as administrator
   2).cd path-to-the-netkvm-driver
   3).rundll32 netkvmco.dll,RegisterNetKVMNetShHelper
3.get the index of virtio-net-pci:
   netsh netkvm show devices
4.Read NetKVM parameter value
  netsh netkvm getparam 0 param=ConnectRate
5.Modify NetKVM parameter value to 100M and check the value from device manager
  netsh netkvm setparam 0 ConnectRate 100
6.Modify NetKVM parameter value to 10G and check the value from device manager
  netsh netkvm setparam 0 ConnectRate 10000
7.Modify NetKVM parameter value to 1G and check the value from device manager
  netsh netkvm setparam 0 ConnectRate 1000
8.netsh netkvm setparam 0 ConnectRate 1001


Actual results:
after step6,all values can be set correctly;
after step7,it prompts in cmd that "The parameter is incorrect";
after step8,the command can be execute successfully and from the device manager the value of "init.ConnetctionRate(Mb" has been set to 1G

Expected results:
the value of "init.ConnetctionRate(Mb" can be set to 1G with step7 instead of step8.
