  Modified files:
    sys/dev/netif/bge    if_bge.c 
  Log:
  - Don't disable interrupt in bge_intr(), just acknowledge it.  This avoids
    potential lose of interrupt when interrupt gets re-enabled, since writing
    to BGE_MBX_IRQ0_LO also serves as interrupt acknowledgment.
  - Move interrupt acknowledgment before reading status block.  This lets us
    read the correct/complete status block.
  - Reset ifnet.if_timer, only if there is nothing pending to be TXed.
