In the list below note that vmnic3 is showing 100Mbps

I checked in the VI client, and it is set to auto-negotiate.
So is the switch.
I have reviewed http://kb.vmware.com/selfservice/viewContent.do?externalId=1004089&sliceId=1
and all seems to be in order.
vmnics 0-2 are on vSwitch1 which has all of the VMs on it, as well as a service console
vmnics 3-5 are on vSwitch2 which has my iSCSI as well as a second service console.
I've tried removing and re-adding vmnic3, but it persists at 100Mbps
I would set it manually to 1000, but the document linked to above, it recommends auto-negotiate. This NIC once did auto-negotiate 1000Mbps.
I have the exact same scenario on another host.
What next?
Thanks,
Magister
