Subject[PATCH v3 0/2] virtio_console: fix replug of virtio console port
Date
This patch series fixes the issue with unplug/replug of a port in virtio
console driver which fails with an error "Error allocating inbufs\n".
Patch 1 makes use of 'virtqueue_detach_unused_buf' function to detach
the unused buffers during port hotunplug time.
Patch 2 updates the next avail index for packed ring code.
Tested the packed ring code with the qemu virtio 1.1 device code posted
here [1].

Changes from v2
Better change log in patch2 - [Greg]
Changes from v1[2]
Make virtio packed ring code compatible with split ring - [Michael]
