  Modified files:
    sys/dev/netif/em     if_em.c 
  Add a workaround for some Lenovo/IBM laptops' onboard em(4).
  Without this workaround, em(4) is extremely slow when TXing packets, though
  polling(4) seems to make the situation better, the speed is still far from
  expectation for 100BaseTX-FDX network.
