    if_indextoname(3): Correct the RFC in a comment
    
    RFC 2533 refers to 'A Syntax for Describing Media Feature Sets',
    which is wrong since the correct reference should be
    RFC 2553 'Basic Socket Interface Extensions for IPv6'.
    
    Obtained from:  OpenBSD
    
    (cherry picked from commit fa556e83be84c588704ce0d652803eb7187bcd30)
