How to change VMINIPORT MaxSpeed

NTDEV
1

I wrote params in inf file to change the transport speed. but when I change
the speed manualy,virtual NIC would stop and restart . this is not allowed
in my app env.and i manually change the speed is also a bad way.
so how can I change the speed use IOCTL in the NDIS virtual miniport
automaticly,and then show it in the status panel??

thanks!!!

Add some custom OID (variant: a WMI accessible OID)
and send it from usermode.

Variant: make your custom Advanced tab for Device manager,
and send this OID from there, rather than changing the value in the registry.

Then your driver should make indication of the new speed.
For NDIS 6 this is NDIS_STATUS_LINK_SPEED_CHANGE,
for NDIS 5 maybe you need to simulate cable disconnect and reconnect.

If you are an NDIS6 miniport, send up an NDIS_STATUS_LINK_STATE status indication.
Otherwise, send an NDIS_STATUS_LINK_SPEED_CHANGE indication.
