ae69ad884d After inpcb route caching was put back in place there is no need for
flowtable anymore (as flowtable was never considered to be useful in
the forwarding path).

114350b9de Replace DPSRCS that work fine in SRCS.
This is so that 'make depend' is not a required build step in these
files.

DPSRCS is overall unneeded.  DPSRCS already contains SRCS, so anything
which can safely be in SRCS should be.  DPSRCS is mostly just a way to
generate files that should not be linked into the final PROG/LIB.  For
headers and grammars it is safe for them to be in SRCS since they will
be excluded during linking and installation.

The only remaining uses of DPSRCS are for generating .c or .o files that
must be built before 'make depend' can run 'mkdep' on the SRCS c files
list.  A semi-proper example is in tests/sys/kern/acct/Makefile where a
checked-in .c file has an #include on a generated .c file.  The
generated .c file should not be linked into the final PROG though since
it is #include'd.  The more proper way here is just to build/link it in
though without DPSRCS.  Another example is in sys/modules/linux/Makefile
where a shell script runs to parse a DPSRCS .o file that should not be
linked into the module.  Beyond those, the need for DPSRCS is largely
unneeded, redundant, and forces 'make depend' to be ran.  Generally,
these Makefiles should avoid the need for DPSRCS and define proper
dependencies for their files as well.

An example of an improper usage and why this matters is in usr.bin/netstat.
nl_defs.h was only in DPSRCS and so was not generated during 'make all',
but only during 'make depend'.  The files including it lacked proper
depenencies on it, which forced running 'make depend' to workaround that
bug.  The 'make depend' target should mostly be used for incremental build
help, not to produce a working build.  This specific example was broken in
the meta build until r287905 since it does not run 'make depend'.

The gnu/lib/libreadline/readline case is fine since bsd.lib.mk has 'OBJS:
SRCS:M*.h' when there is no .depend file.

45c203fce2 Remove AppleTalk support.
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.

2c284d9395 Remove IPX support.
IPX was a network transport protocol in Novell's NetWare network operating
system from late 80s and then 90s. The NetWare itself switched to TCP/IP
as default transport in 1998. Later, in this century the Novell Open
Enterprise Server became successor of Novell NetWare. The last release
that claimed to still support IPX was OES 2 in 2007. Routing equipment
vendors (e.g. Cisco) discontinued support for IPX in 2011.

Thus, IPX won't be supported in FreeBSD 11.0-RELEASE.

5d6d7e756b o Revamp API between flowtable and netinet, netinet6.
- ip_output() and ip_output6() simply call flowtable_lookup(),
    passing mbuf and address family. That's the only code under
    #ifdef FLOWTABLE in the protocols code now.
o Revamp statistics gathering and export.
  - Remove hand made pcpu stats, and utilize counter(9).
  - Snapshot of statistics is available via 'netstat -rs'.
  - All sysctls are moved into net.flowtable namespace, since
    spreading them over net.inet isn't correct.
o Properly separate at compile time INET and INET6 parts.
o General cleanup.
  - Remove chain of multiple flowtables. We simply have one for
    IPv4 and one for IPv6.
  - Flowtables are allocated in flowtable.c, symbols are static.
  - With proper argument to SYSINIT() we no longer need flowtable_ready.
  - Hash salt doesn't need to be per-VNET.
  - Removed rudimentary debugging, which use quite useless in dtrace era.

The runtime behavior of flowtable shouldn't be changed by this commit.

6aa83769fd After r232745, which makes sure __bswap16(), ntohs() and htons() return
__uint16_t, we can partially undo r228668.

Note the remark "Work around a clang false positive with format string
warnings and ntohs macros (see LLVM PR 11313)" was actually incorrect.

Before r232745, on some arches, the ntohs() macros did in fact return
int, not uint16_t, so clang was right in warning about the %hu format
string.

07b202a847 Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to
get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.

Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang       (disables -Werror)
- NO_WCAST_ALIGN.clang  (disables -Wcast-align)
- NO_WFORMAT.clang	(disables -Wformat and friends)
- CLANG_NO_IAS		(disables integrated assembler)
- CLANG_OPT_SMALL	(adds flags for extra small size optimizations)

As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf!  For clang, use the following:

CC=clang
CXX=clang++
CPP=clang-cpp

100b98db75 Add support for printing IPSEC protocol stats if the kernel was compiled
with FAST_IPSEC rather than the KAME IPSEC stack.

Note that the output of "netstat -s -p ipsec" differs depending on which
stack is compiled into the kernel since they each keep different stats.
This delta also adds the "esp", "ah", and "ipcomp" protocol stats, which
are also available when the kernel is compiled with the FAST_IPSEC stack
(e.g. "netstat -s -p esp").

6b463eed3a Merge bpfstat's functionality into the netstat(1) utility. This adds
a -B option which causes bpf peers to be printed. This option can be
used in conjunction with -I if information about specific interfaces
is desired. This is similar to what NetBSD added to their version of
netstat.

c8e6b6899a Modify "netstat -mb" to use libmemstat(3) when acting on a live system,
with a number of positive benefits:

- Start using UMA(9) statistics for mbufs and clusters, which avoids
  using the mbuf allocator statistics which suffer from races under
  load on SMP.  This should eliminate "negative" mbuf counts in
  netstat -mb.

- We are now able to track cached (free) mbufs and clusters and count
  it towards memory allocated by the network stack.

- We are now also able to track memory allocated to mbuf tags since
  libmemstat(3) can also query malloc(9).  We don't print this except
  as part of the total (for now - #if 0).

- We are now able to track mbuf/cluster/packet allocation failures,
  although they are not currently printed (#if 0).

- Don't print out sfbuf statistics when running on a kernel core, as
  currently that code is able only to query sysctl for statistics.
