  8. Only core revisions older than 4 use BGMAC_CMDCFG_SR_REV0. This mainly
  9. fixes support for BCM4708A0KF SoCs with Ethernet core rev 5 (it means
  10. only some devices as most of BCM4708A0KF-s got core rev 4).
  11. This was tested for regressions on BCM47094 which doesn't seem to care
  12. which bit gets used.
