Mateusz Guzik 71a1539e37 inet6: fix a LOR between rip and rawinp 
Running sys/netpfil/pf/fragmentation v6 results in:

lock order reversal:
 1st 0xfffffe00050429a8 rip (rip, sleep mutex) @ /usr/src/sys/netinet6/raw_ip6.c:803
 2nd 0xfffff8009491e1d0 rawinp (rawinp, rw) @ /usr/src/sys/netinet6/raw_ip6.c:804

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
