65f2c0ff58 Merge r207585 from cas(4):
- Don't probe for PHYs if we already know to use a SERDES. Unlike as with
  cas(4) this only serves to speed up the the device attach though and can
  only be determined via the OFW device tree but not from the VPD.
- Don't touch the MIF when using a SERDES.
- Add some missing bus space barriers, mainly in the PCS code path.

9ba2b298df - Initialize the ifnet structure, especially if_dname, before probing
the PHYs as some PHY drivers use it (but probably shouldn't). How
  gem(4) has worked with brgphy(4) on powerpc without this so far is
  unclear to me.
- Introduce a dying flag which is set during detach and checked in
  gem_ioctl() in order to prevent active BPF listeners to clear
  promiscuous mode which may lead to the tick callout being restarted
  which will trigger a panic once it's actually gone.
- In gem_stop() reset rather than just disable the transmitter and
  receiver in order to ensure we're not unloading DMA maps still in
  use by the hardware. [1]
- The blanking time is specified in PCI clocks so we should use twice
  the value when operating at 66MHz.
- Spell some 2 as ETHER_ALIGN and a 19 as GEM_STATUS_TX_COMPLETION_SHFT
  to make the actual intentions clear.
- As we don't unload the peak attempts counter ignore its overflow
  interrupts.
- Remove a stale setting of a variable to GEM_TD_INTERRUPT_ME which
  isn't used afterwards.
- For optimum performance increment the TX kick register in multiples
  of 4 if possible as suggested by the documentation.
- Partially revert r164931; drivers should only clear the watchdog
  timer if all outstanding TX descriptors are done.
- Fix some debugging strings.
- Add a missing BUS_DMASYNC_POSTWRITE in gem_rint().
- As the error paths in the interrupt handler are generally unlikely
  predict them as false.
- Add support for the SBus version of the GEM controller. [2]
- Add some lock assertions.
- Improve some comments.
- Fix some more or less cosmetic issues in the code of the PCI front-end.
- Change some softc members to be unsigned where more appropriate and
  remove unused ones.
