svn commit: r185344 - in head/sys: netinet netinet6

[Bjoern A. Zeeb]

Author: bz
Date: Wed Nov 26 20:52:26 2008
New Revision: 185344
URL: http://svn.freebsd.org/changeset/base/185344

Log:
  Remove in6_pcbdetach() as it is exactly the same function
  as in_pcbdetach() and we don't need the code twice.
  
  Reviewed by:	rwatson
  MFC after:	6 weeks (*)
  (*) possibly need to leave a stub wrapper in 7 to keep the symbol.
