How about at the very end of sis_intr(), as a new "else" branch of the
queue length check, like this:
if (ifp->if_snd.ifq_head != NULL)
sis_start(ifp);
+
else
+
if_tx_ready(ifp);
That doesn't seem to be in the codepath that gets executed on each poll,
right?

They are amazing, I'm really glad the folks on freebsd-small have
pointed us at them. Only downside is that you go blind if you look at
the case for too long :-)
