    sys/dev/em           if_em.c if_em.h if_em_hw.h 
  Sync with HEAD. Revisions merged:
    - rev. 1.76. Removed FreeBSD 4.x code.
    - rev. 1.77, 1.79. Together with rev. 1.71 (already merged) this
      fixes problems when some code is executed in driver when
      em_process_receive_interrupts() drops lock. This can occur
      at runtime, when polling(4) mode is changed to interrupt driver
      or vise versa, but more likely this can happen when administrator
      issues some ifconfig commands.
    - rev. 1.78. In em_process_receive_interrupts(), call bus_dmamap_sync()
      for the descriptors set each time we modify one descriptor, instead
      of doing it only at the function exit.
    - rev. 1.80. Loop in em_intr() until interrupt cause register is clear,
      don't mask overrun interrupt.
    - rev. 1.81. Several locking and other fixes.
  See particular revision logs for more detailed information.
