This fixes 3 issues: - prevent admin commands on one VF blocking another: prevents a bad VF from blocking a good one, as well as fixing a scalability issue with large # of VFs - correctly return error on command failure on octeon: currently if any commands fail we treat it as success - fix modpost warning when building virtio_dma_buf: harmless, but the fix is trivial Signed-off-by: Michael S.
