  Log:
  The maxsegsz of a dma tag created in de(4) is TULIP_DATA_PER_DESC bytes.
  In Rx path it allocates a new mbuf with m_getcl(9) so the length of
  the mbuf is MCLBYTES which is greater than a segment size specified by
  the dma tag. This segment size mismatch caused a voluntary panic.
  Fix the panic by settting the mbuf length to TULIP_DATA_PER_DESC.
