--- Comment #5 from Stephen Hurd <shurd at FreeBSD.org> ---
Can you try with this:

Index: sys/net/iflib.c
===================================================================

        }
 done:
+       MPASS(n == i == 0);
        DBG_COUNTER_INC(rxd_flush);
        if (fl->ifl_pidx == 0)
                pidx = fl->ifl_size - 1;

It looks like ifl_credits could get out of sync in the error paths here, but
I'm not sure you're hitting any of them.
