[RFC PATCH 0/3] Sharing MSIX irq for tx/rx queue pairs
Hi all:
This series try to share MSIX irq for each tx/rx queue pair. This is
done through:
- introducing virtio pci channel which are group of virtqueues that
sharing a single MSIX irq (Patch 1)
- expose channel setting to virtio core api (Patch 2)
- try to use channel setting in virtio-net (Patch 3)
For the transport that does not support channel, channel paramters
were simply ignored. For
