A practicality here:

The assumption to fail for physical channel allocation at .tx_submit()
is already in the first patch adding the driver.

Should I squash all the icremental improvements into the original
driver, convert to fail at .prep() and resubmit to make all of this
easier, or do you want me to refactor the patch stack, or refactor
from patch 11/12 or...?

Yours,
