Make some small performance tweaks to the tl driver. This should hopefully
close PR #13757, however I'm waiting on user feedback before declaring the
PR officially closed. Among other things, this improves UDP transmit
performance, and tx underruns are now detected and the TX start threshold
adjusted accordingly.
