    ether_addr_equal: Optimize implementation, remove unused compare_ether_addr · 0d74c42f
    Joe Perches authored
    Add a new check for CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS to reduce
    the number of or's used in the ether_addr_equal comparison to very
    slightly improve function performance.
    
    Simplify the ether_addr_equal_64bits implementation.
    Integrate and remove the zap_last_2bytes helper as it's now
    used only once.
    
    Remove the now unused compare_ether_addr function.
    
    Update the unaligned-memory-access documentation to remove the
    compare_ether_addr description and show how unaligned accesses
    could occur with ether_addr_equal.
