[PATCH stable v2 0/3] virtio-net: backport error handling bugfix

["Michael S. Tsirkin" <mst@redhat.com>]

Error handling for virtio-net mergeable buffers was broken
for a long time. Backport recent bugfix to a stable
kernel.

Please note that it's really a single change split out for ease of
review - that's why 2/2 is here even though it's not
stricktly a bugfix - the code becomes too confusing without it.

Please review and consider for stable.

Changes from v1:
	- include patch 3/3 as suggested by Michael
	- tweak commit log as suggested by Jason

Michael S. Tsirkin (3):
  virtio_net: fix error handling for mergeable buffers
  virtio-net: make all RX paths handle errors consistently
  virtio_net: don't leak memory or block when too many frags
