   4 Subject: [PATCH 2/5] leds: trigger: netdev: Drop NETDEV_LED_MODE_LINKUP from
   5  mode
   6
   7 Putting NETDEV_LED_MODE_LINKUP in the same list of the netdev trigger
   8 modes is wrong as it's used to set the link state of the device and not
   9 to set a blink mode as it's done by NETDEV_LED_LINK, NETDEV_LED_TX and
  10 NETDEV_LED_RX. It's also wrong to put this state in the same bitmap of the
  11 netdev trigger mode and should be external to it.
  12
  13 Drop NETDEV_LED_MODE_LINKUP from mode list and convert to a simple bool
  14 that will be true or false based on the carrier link. No functional
  15 change intended.
