Doc Type: Bug Fix
Doc Text:
Cause: Bug in INF file incorrectly indicated 1G connection rate. Consequence: While the connection rate could be set from device manager, it was impossible to set 1G rate using command line tool (netsh with NetKVM plugin). Fix: Set the correct connection rate in INF file Result: NetSH can set NIC connection rate correctly.

Description lijin 2013-07-10 07:50:43 UTC
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):

How reproducible:

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.

Comment 4 Yan Vugenfirer 2013-07-29 12:15:56 UTC
Fixed for OSes Vista and up.

Comment 5 lijin 2013-08-08 06:57:16 UTC


Reproduced this issue on build65
Verified this issue on build66

steps same as comment #0

Actual Results:
On build65, after "netsh netkvm setparam 0 ConnectRate 1000",it prompt "The parameter is incorrect";
On build66,win2012,win2k8R2,win2k8-64,win8-64 and win7-64 can set the connectrate to 1G correctly;as for guest win7-32,win8-32 and win2k8-32,there is bug 988302 to track another issue.

Based on above,this issue has been fixed already.
