How does the notion of a device which is both a bond and a leg of a bond fit with Alex's recent discussions about feature propagation? Which propagation rules will apply to VirtIO master? Meaning of the flags on a software upper device may be different. Why muddy the architecture like this and not introduce a synthetic bond device? _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
