Add GRE-in-UDP encapsulation support as defined in RFC8086.2019-04-24T09:05:45ZAndrey V. Elsukovae@FreeBSD.org2019-04-24T09:05:45Zurn:sha1:aee793eec92c50c82e612302dc8e56abba4efae9
This GRE-in-UDP encapsulation allows the UDP source port field to be
used as an entropy field for load-balancing of GRE traffic in transit
networks. Also most of multiqueue network cards are able distribute
incoming UDP datagrams to different NIC queues, while very little are
able do this for GRE packets.
When an administrator enables UDP encapsulation with command
`ifconfig gre0 udpencap`, the driver creates kernel socket, that binds
to tunnel source address and after udp_set_kernel_tunneling() starts
receiving of all UDP packets destined to 4754 port. Each kernel socket
maintains list of tunnels with different destination addresses. Thus
when several tunnels use the same source address, they all handled by
single socket. The IP[V6]_BINDANY socket option is used to be able bind
socket to source address even if it is not yet available in the system.
This may happen on system boot, when gre(4) interface is created before
source address become available. The encapsulation and sending of packets
is done directly from gre(4) into ip[6]_output() without using sockets.

gcc requires variables to be initialised in two places. One of them
is correctly used only under the same conditional though.
For module builds properly check if the kernel supports INET or INET6,
as otherwise various mips kernels without IPv6 support would fail to build.
Overhaul if_gre(4).2014-11-07T19:13:19ZAndrey V. Elsukovae@FreeBSD.org2014-11-07T19:13:19Zurn:sha1:f325335cafc940e54a1ea56560de6f25340c81b7
Split it into two modules: if_gre(4) for GRE encapsulation and
if_me(4) for minimal encapsulation within IP.
gre(4) changes:
* convert to if_transmit;
* rework locking: protect access to softc with rmlock,
protect from concurrent ioctls with sx lock;
* correct interface accounting for outgoing datagramms (count only payload size);
* implement generic support for using IPv6 as delivery header;
* make implementation conform to the RFC 2784 and partially to RFC 2890;
* add support for GRE checksums - calculate for outgoing datagramms and check
for inconming datagramms;
* add support for sending sequence number in GRE header;
* remove support of cached routes. This fixes problem, when gre(4) doesn't
work at system startup. But this also removes support for having tunnels with
the same addresses for inner and outer header.
* deprecate support for various GREXXX ioctls, that doesn't used in FreeBSD.
Use our standard ioctls for tunnels.
me(4):
* implementation conform to RFC 2004;
* use if_transmit;
* use the same locking model as gre(4);

Remove AppleTalk support.2014-03-14T06:29:43ZGleb Smirnoffglebius@FreeBSD.org2014-03-14T06:29:43Zurn:sha1:45c203fce2d02381f76b2abf80edaea8cf7bc7f8
AppleTalk was a network transport protocol for Apple Macintosh devices
in 80s and then 90s. Starting with Mac OS X in 2000 the AppleTalk was
a legacy protocol and primary networking protocol is TCP/IP. The last
Mac OS X release to support AppleTalk happened in 2009. The same year
routing equipment vendors (namely Cisco) end their support.
Thus, AppleTalk won't be supported in FreeBSD 11.0-RELEASE.
Let modules use the kernel's opt_*.h files if built along with2005-10-14T23:30:17ZYaroslav Tykhiyytykhiy@gmail.com2005-10-14T23:30:17Zurn:sha1:822923447e454b30d310cb46903c9ddeca9f0a7a
the kernel by wrapping all targets for fake opt_*.h files in
.if defined(KERNBUILDDIR). Thus, such fake files won't be
created at all if modules are built with the kernel.
Some modules undergo cleanup like removing unused or unneeded
options or .h files, without which they wouldn't build this way
or the other.
