ONLY way I can get this working is one of two ways. I have to unplug power, not just shut it down. I need to kill power from the board entirely. Wait 10secs, then plug it back in. Then upon starting up, its set to gigabit with no issues. Other way is to change a setting in Bios which when you exit/save it causes it to kill power to the board for a second. So the fact that killing power to the board fixes it, tells me its some hardware or firmware level issue, clearly not the driver.
Im having the same issues, the only way ive been able to get the NIC to negotiate back to 100Mb/s is to disable the card and then re-enable it. However after a little while it will jump back to 10 Mb/s. I have a dell optiplex 9010 like every one else here. It does look like an actual issue.
It is recommended to start the KVM session in S0, excluding use cases that require starting the session in Sx. In Sx the network speed is set at 10Mbps. Opening a session in Sx and then powering up the machine will keep the original Sx network speed of 10Mbps until the session ends and there is a reboot or driver initialization. Moving to S0 before opening a redirection session avoids this network speed limitation.
