[PATCH v1 1/3] virtio-net: Using single MSIX IRQ for TX/RX Q pair

Ported earlier patch from Jason Wang (dated 12/26/2014). This patch tries to reduce the number of MSIX irqs required for virtio-net by sharing a MSIX irq for each TX/RX queue pair through channels. If transport support channel, about half of the MSIX irqs were reduced. Signed-off-by: Ravi Kerur
