Author: tuexen Date: Wed Aug 24 06:22:53 2016 New Revision: 304736 URL: https://svnweb.freebsd.org/changeset/base/304736 Log: When aborting an association, send the ABORT before notifying the upper layer. For the kernel this doesn't matter, for the userland stack, it does. While there, silence a clang warning when compiling it in userland.
