Subject: [PATCH v2] net: phy: leds: Don't make our own link speed names
Date:   Thu, 8 Nov 2018 15:03:10 -0600

The phy core provides a handy phy_speed_to_str() helper, so use that
instead of doing our own formatting of the different known link speeds.
To do this, increase PHY_LED_TRIGGER_SPEED_SUFFIX_SIZE to 11 so we can fit
'Unsupported' if necessary.

v2: Increase PHY_LED_TRIGGER_SPEED_SUFFIX_SIZE to fit 'Unsupported'.
