* remotes/mcayland/tags/qemu-sparc-20190702:
  sunhme: ensure that RX descriptor ring overflow is indicated to client driver
  sunhme: fix return values from sunhme_receive() during receive packet processing
  sunhme: flush any queued packets when HME_MAC_RXCFG_ENABLE bit is raised
  sunhme: fix incorrect constant in sunhme_can_receive()
  sunhme: add trace event for logging PCI IRQ
  sun4m: set default display type to TCX
