[7.509][Bug?] auto-negotiation not working on Intel 82574L NIC w VLAN

I just noticed tonight that my INT NIC was running at 100/Full; I've now set it to 1000/Full manually.

NIC is an Intel 82574L gigE (onboard my MSI IM-945GSE-A motherboard)
Switch is a Netgear GS108T

I'm using Astaro VLANs (3 VLANs on INT NIC)

I'm not sure if this is a problem with the e1000e NIC driver, VLAN support, or the switch.

Just for guys who may arrive here after searching:
1.there's kernel bug in intel 82574L e1000e driver on centos 6(MSI/MSI-X interrupts issue), we can resolve this by install kmod-e1000e package from ELrepo.org and later add pcie_aspm=off e1000e.IntMode=1,1 e1000e.InterruptThrottleRate=10000,10000 acpi=off to kernel parameters. You can read more info Intel e1000e driver bug on 82574L Ethernet controller causing network blipping.
2.For the high Tx traffic, this was caused by port 53 dns flooding attack. I've resolved this by writing some iptable rules. More info here: port 53 dns flooding attack

Thanks, but I'm not sure that is the same issue.
Also the web page seems to indicate that autoneg be turned off, so it doesn't really fix my problem.
