    e1000:
       Calculating this pointer gives undefined behaviour when (last == -1)
       (it is before the buffer).  The pointer is always followed.  Panics
       occurred when it points to an unmapped page.  Otherwise, the pointed-to
       garbage tends to not have the E1000_TXD_STAT_DD bit set in it, so in the
       broken case the loop was usually null and the function just returned, and
       this was acidentally correct.
