[PATCH] enable getsockopt() for IP_NODEFRAG

[Michael Kerrisk <mtk.manpages@gmail.com>]

Hello Jiri

While integrating your man-pages patch for IP_NODEFRAG, I noticed 
that this option is settable by setsockopt(), but not gettable by 
getsockopt(). I suppose this is not intended. The (untested, 
trivial) patch below adds getsockopt() support.

The patch is against 2.6.36-rc3.

Cheers,

Michael

PS I've just configured Thunderbird on this machine, hopefully the 
patch is not mangled. Please let me know if there are problems.
