   4 Subject: [PATCH] net: dsa: b53: Drop BCM5301x workaround for a wrong CPU/IMP

  10 On BCM5301x port 8 requires a fixed link when used.
  11
  12 Years ago when b53 was an OpenWrt downstream driver (with configuration
  13 based on sometimes bugged NVRAM) there was a need for a fixup. In case
  14 of forcing fixed link for (incorrectly specified) port 5 the code had to
  15 actually setup port 8 link.
  16
  17 For upstream b53 driver with setup based on DT there is no need for that
  18 workaround. In DT we have and require correct ports setup.
