Hi Mika

There are a few other places which should be updated when a new speed
is added:

https://elixir.bootlin.com/linux/v6.18.4/source/drivers/net/phy/phy-core.c#L18
https://elixir.bootlin.com/linux/v6.18.4/source/drivers/net/phy/phy_caps.c#L9
https://elixir.bootlin.com/linux/v6.18.4/source/drivers/net/phy/phy_caps.c#L30
