Follow-up Comment #2, bug #51663 (project lwip):

Thank you. Yes I was seeing delays of 20 seconds on the wifi TX link layer,
and the pre-existing pbuf ref guard was needed. The etharp layer can also
queue buffers (defer transmission) and that also tickles this code path, so it
is not exclusive to marginal wifi links.
