    realtek: rtl838x_eth: Use printk MAC specifier instead of raw hex
    
    The linux kernel printk has a MAC address specifier `%pM` that can be
    used to pretty-print MAC addresses.  We should use this specifier when
    printing MAC addresses for humans since that ensure the appearance that
    people are used to.
    
    Fixes #21796
