55fb7d688b Now, after r263102 we have ifi_oqdrops in if_data, restore printing of 
output queue drops in netstat(1).

No driver, neither kernel fills this field in if_data, yet.

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.

b245f96c44 Since 32-bit if_baudrate isn't enough to describe a baud rate of a 10 Gbit 
interface, in the r241616 a crutch was provided. It didn't work well, and
finally we decided that it is time to break ABI and simply make if_baudrate
a 64-bit value. Meanwhile, the entire struct if_data was reviewed.

o Remove the if_baudrate_pf crutch.

o Make all fields of struct if_data fixed machine independent size. The
  notion of data (packet counters, etc) are by no means MD. And it is a
  bug that on amd64 we've got a 64-bit counters, while on i386 32-bit,
  which at modern speeds overflow within a second.

  This also removes quite a lot of COMPAT_FREEBSD32 code.

o Give 16 bit for the ifi_datalen field. This field was provided to
  make future changes to if_data less ABI breaking. Unfortunately the
  8 bit size of it had effectively limited sizeof if_data to 256 bytes.

o Give 32 bits to ifi_mtu and ifi_metric.
o Give 64 bits to the rest of fields, since they are counters.

__FreeBSD_version bumped.

fc47e028bb Use more fine-grained kvm(3) symbol lookup: routing code retrieves only 
necessary symbols needed per subsystem. Main kvm(3) init is now delayed
as much as possbile. This finally fixes performance issues reported in
kern/167204.

Some global variables eliminated.

84c1edcbad Rewrite netstat/if.c to use getifaddrs(3) and getifmaddrs(3) instead of 
libkvm digging in kernel memory. This is possible since r231506 made
getifaddrs(3) to supply if_data for each ifaddr.

  The pros of this change is that now netstat(1) doesn't know about kernel
struct ifnet and struct ifaddr. And these structs are about to change
significantly in head soon. New netstat binary will work well with 10.0
and any future kernel.

  The cons is that now it isn't possible to obtain interface statistics
from a vmcore.

  Functions intpr() and sidewaysintpr() were rewritten from scratch.

  The output of netstat(1) has underwent the following changes:

1) The MTU is not printed for protocol addresses, since it has no notion.
   Dash is printed instead. If there would be a strong desire to return
   previous output, it is doable.
2) Output interface queue drops are not printed. Currently this data isn't
   available to userland via any API. We plan to drop 'struct ifqueue' from
   'struct ifnet' very soon, so old kvm(3) access to queue drops is soon
   to be broken, too. The plan is that drivers would handle their queues
   theirselves and a new field in if_data would be updated in case of drops.
3) In-kernel reference count for multicast addresses isn't printed. I doubt
   that anyone used it. Anyway, netstat(1) is sysadmin tool, not kernel
   debugger.

d6d3f01e0a Merge the projects/pf/head branch, that was worked on for last six months, 
into head. The most significant achievements in the new code:

 o Fine grained locking, thus much better performance.
 o Fixes to many problems in pf, that were specific to FreeBSD port.

New code doesn't have that many ifdefs and much less OpenBSDisms, thus
is more attractive to our developers.

projects/pf/head branch. And for reference, here is exact list of

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

feda1a4372 Restore netstat -M functionality for most statistics on core dumps. In 
general, when support was added to netstat for fetching data using sysctl,
no provision was left for fetching equivalent data from a core dump, and
in fact, netstat would _always_ fetch data from the live kernel using
sysctl even when -M was specified resulting in the user believing they
were getting data from coredumps when they actually weren't.  Some specific
changes:
- Add a global 'live' variable that is true if netstat is running against
  the live kernel and false if -M has been specified.
- Stop abusing the sysctl flag in the protocol tables to hold the protocol
  number.  Instead, the protocol is now its own field in the tables, and
  it is passed as a separate parameter to the PCB and stat routines rather
  than overloading the KVM offset parameter.
- Don't run PCB or stats functions who don't have a namelist offset if we
  are being run against a crash dump (!live).
- For the inet and unix PCB routines, we generate the same buffer from KVM
  that the sysctl usually generates complete with the header and trailer.
- Don't run bpf stats for !live (before it would just silently always run
  live).
- kread() no longer trashes memory when opening the buffer if there is an
  error on open and the passed in buffer is smaller than _POSIX2_LINE_MAX.
- The multicast routing code doesn't fallback to kvm on live kernels if
  the sysctl fails.  Keeping this made the code rather hairy, and netstat
  is already tied to the kernel ABI anyway (even when using sysctl's since
  things like xinpcb contain an inpcb) so any kernels this is run against
  that have the multicast routing stuff should have the sysctls.
- Don't try to dig around in the kernel linker in the netgraph PCB routine
  for core dumps.

Other notes:
- sctp's PCB routine only works on live kernels, it looked rather
  complicated to generate all the same stuff via KVM.  Someone can always
  add it later if desired though.
- Fix the ipsec removal bug where N_xxx for IPSEC stats weren't renumbered.
- Use sysctlbyname() everywhere rather than hardcoded mib values.

93547b07b9 Use a periodic itimer instead of repeated calls to alarm() in 
sidewaysintpr().  This increases the accuracy of the per-interval
counts when they are interpreted as rates.  Repeated calls to alarm(n)
give an average interval that is about 2 ticks larger than n and has
a large variance.  Periodic itimers normally get the average almost
right but have similarly large variance (due to scheduling delays).

Statistics utilities should use clock_gettime() to determine the
actual interval, but it is still useful to maximize the accuracy of
the interval, especially for cases like netstat -w where counts are
displayed so the program cannot hide the inaccuracy in a rate
conversion.
