The bit I was referring to not setting would handle that. By disabling the DTXSWC local loopback bit the PF will not send anything to the VFs or visa versa. > Yes, lets do that.

Well whenever I can get to it I will try to add that support. In the meantime I believe there is a BOF session covering "Virtual Ethernet switch enhancements and configuration" at the Linux Plumbers Conf that will cover some of this so hopefully we can come up with a solid plan on how to address this.
