Abstract
Hardware transmit and/or receive queues in a self-virtualizing IO resource are virtualized to effectively abstract away resource-specific details for the self-virtualizing IO resource. By doing so, a logical partition may be permitted to configure and access a desired number of virtual transmit and/or receive queues, and have an adjunct partition that interfaces the logical partition with the self-virtualizing IO resource handle the appropriate mappings between the hardware and virtual queues.
