ARP forwards with Quad 10GB Interfaces

Hi All,

I have OVSx86 running on an Oracle X7-2 and there is a different behaviour with ARP packets between the on-board interfaces and the PCI Quad 10GB/Dual 40GB http://www.oracle.com/us/products/servers-storage/networking/10gbor40gbethernetadapter-faq-2968068.pdf

http://www.oracle.com/us/products/servers-storage/networking/10gbor40gbethernetadapter-faq-2968068.pdf

When we use on-board interfaces ARP packets are passed by dom0 to domUs

When we use the PCI interfaces ARP packets are *not* passed to the domUs

Is there some configuration or sysctl values to be set that could help?  Any helps or pointers would be a great help.

Kind regards,

Iain
