ip6opt.c

[Eitan Adler]

Hi all,

DragonFly recently committed the following change and it seems that it
applies to us as well.

http://gitweb.dragonflybsd.org/dragonfly.git/blobdiff/5764e12516158974fac10d50dbd2df76ce1ab007..98651c6e0e1c3b7a6b8650b55b473fcc745a22b7:/lib/libc/net/ip6opt.c

Should I commit it?
