  10 There is a downstream patch which adds a new interface type -
  11 PHY_INTERFACE_MODE_2500SGMII (which is really the same one as
  12 PHY_INTERFACE_MODE_2500BASEX).
  13
  14 We backported from upstream the following phylink patch which, of
  15 course, does not treat the PHY_INTERFACE_MODE_2500SGMII interface mode
  16 in a switch case statement.
  17         34ae2c09d46a ("net: phylink: add generic validate implementation")
  18
  19 Because of this, we get the following build warning.
  20
  21 drivers/net/phy/phylink.c: In function ‘phylink_get_linkmodes’:
  22 drivers/net/phy/phylink.c:322:2: warning: enumeration value ‘PHY_INTERFACE_MODE_2500SGMII’ not handled in switch [-Wswitch]
  23   322 |  switch (interface) {
  24       |  ^~~~~~
  25
  26 Fix it by treating the new interface mode in the switch-case statement.
