bge: Enable "tagged status" on non-BCM5788 and non-BCM5700 chips

By using "tagged status", we could:
- Detect whether the interrupt is for us or not.
- Avoid MAC_STS register read upon every interrupt.

Some implementation note:
- Interrupt must be disabled during interrupt handing, if "tagged status"
  is used, else the interrupt will be kept asserted.  This is the case at
  least on BCM5750 AX/BX.
- Coalesce parameters during interrupt must be properly configured; when
  "tagged status" is used we have "in interrupt" state.

Tunable hw.bgeX.status_tag is added to prevent driver from using "tagged
status".  hw.bgeX.{rx,tx}_coal_bds_int and hw.bgeX.{rx,tx}_coal_ticks_int
sysctls are added to tune "in interrupt" coalesce parameters.

implementation, if the tcp_output() sends no segments, the current
recovery transmit process will stop immediately.  This could stop ACK
clock and cause timeout retransmit, which could be avoided, if the
