How is tx-flushing supposed to work now?

[Ben Greear]

When we have multiple vdevs, and the 10.4.3 firmware with the tx-push logic,
how is flushing supposed to work?

First, when we get a flush, should we first purge any frames not yet pushed
to the firmware?

And second, what keeps other vdevs from continuing to transmit frames while one
vdev is trying to be flushed?

Thanks,
Ben
