ip: consolidate IPv6 link-local-address functions.
Two codes diverged in the packet processor And sorry I could not use them both Long I stood being but one developer And studied one as far as I could To where the code said bitwise OR Then took the other, as just could see, And having perhaps the better bit, Because it followed the RFC And used the cryptic XOR in C, Had run them both a fair bit. And both equally ran that morning With packets dropped and flowing. Oh, I flagged the first for dropping! Yet knowing bug leads to debuging I hoped I'd never be returning. I shall be commiting this with a sigh Somewhere ages and ages hence: Two codes diverged by a bit, and I, I made the packets flow on by, And that has made all the difference.
