      net/macb: Only adjust tx_clk on link change · 2c29b235
      Jaeden Amero authored
      
      
      The PHY state machine (in drivers/net/phy/phy.c) will unconditionally
      call phydev->adjust_link (macb_handle_link_change) when polling in the
      PHY_CHANGELINK state. As currently written, macb always ends up
      requesting a new tx_clk frequency in macb_handle_link_change. It is a
      waste of time to request a new tx_clk frequency if the link state hasn't
      changed, as the tx_clk will already be configured properly.
      
      Let's only request a new tx_clk clock frequency when necessary.
