rstone created this revision. rstone added a reviewer: jfvogel. rstone added a subscriber: freebsd-net. REVISION SUMMARY The VF drivers do not have unrestricted access to the hardware. To configure the VF (e.g. set the MAC address), they are required to send a message the PF requesting the configuration. These messages are passed over the "Virtual Channel" (VC). Add the infrastructure required to receive Admin Queue interrupts indicating that a VC message has been received. Also add functions for sending responses back to the VFs. At this stage no VC messages are actually handled. Implementation of individual VC messages will be added in subsequent commits.
