MFC: r223951

Partially merge r223648 and r223949 from gem(4) (committed to stable/8 in
r224367):
- Consistently use the newly introduced sc_mac_rxcfg throughout the driver
  instead of reading the old content of CAS_MAC_RX_CONF.
- Increment if_iqdrops instead of if_ierrors in case of RX buffer allocation
  failure.
- According to the Cassini datasheet the RX MAC should also be disabled in
  cas_setladrf() before changing its configuration.
- Add error messages to gem_disable_{r,t}x() and take advantage of these
  throughout the driver instead of duplicating their functionality all over
  the place.

MFC: r247579

- Move reporting of failures to disable RX/TX MAC under bootverbose as at
  least the Saturn chips of 501-6738 cards may fail to do so the first
  time, which isn't fatal though.
  Reported by: Paul Keusemann
- Explain why we don't enable infinite bursts on sparc64.
- Given that these chips support memory write invalidate, make sure that
  it's enabled in the command register. Also make sure that PERR# and
  SERR# assertion is enabled.
