networkcard driver problem

Hi,

i have a problem with the network card (Intel® (ESB2/Gilgal) 82563EB Dual-Port Gigabit Ethernet Controller) when i install Proxmox VE 3.1. I only have 100 mbit link, but there real speed is 1000 mbit. With Proxmox VE 3.0 i have 1000 mbit.

I got this error in Proxmox VE 3.1 when i type mii-tool (only first plugged in but when all plugged in i have also only 100mbit):

SIOCGMIIREG on eth0 failed: Input/output error
SIOCGMIIREG on eth0 failed: Input/output error
eth0: negotiated 100baseTx-FD flow-control, link ok
SIOCGMIIREG on eth1 failed: Input/output error
SIOCGMIIREG on eth1 failed: Input/output error
eth1: no link

and i got this when i type it in Proxmox VE 3.0:

SIOCGMIIREG on eth0 failed: Input/output error
SIOCGMIIREG on eth0 failed: Input/output error
eth0: negotiated 1000baseT-FD flow-control, link ok
SIOCGMIIREG on eth1 failed: Input/output error
SIOCGMIIREG on eth1 failed: Input/output error
eth1: no link

My Mainboard is Supermicro x7db8 and i saw that the networkcard is using the e1000e drivers. I found in the internet there is a problem with mii-tool and the e1000e driver.

How can i fix this?

Thanks for help.
