When sending control commands, virtio net sets up several buffers for DMA. The buffers are all part of the net device which means it's actually allocated by kvmalloc so it's in theory (on extreme memory pressure) possible to get a vmalloc'ed buffer which on some platforms means we can't DMA there. Fix up by moving the DMA buffers into a separate structure. Reported-by: NMikulas Patocka <mpatocka@redhat.com> Suggested-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NMichael S.
