Virtual Connect and ESXi 4.1 - No Network Performance Statistics

[Nick Salty]

Hi All,
I am running several BL460 G6 ESXi 4.1 Hosts, and have configured Virtual Connect in the C7000 Enclosure.
Everything appears to work ok, but when I look at the Performance graphs for Network in ESXi, I see no Network Performance statistics at all. None.

Has anyone else observed this problem?
I actually saw the Same issue on the HP stand at the vmware event in Sydney last year, but they didn't know if there was a fix.

I have searched high and low for a patch or update, but have not yet found one. I am running build 348418 of ESXi4.1 (latest).
