 * The message header format described here is used for messages that are
 * passed between the PF and the VF.  To allow for messages larger then
 * mailbox size we will provide a message with the above header and it
 * will be segmented and transported to the mailbox to the other side where
 * it is reassembled.  It contains the following fields:
 * Length: Length of the message in bytes excluding the message header
 * Flags: TBD
 * Type/ID: These will be the message/argument types we pass
