6615ed4c61 Make struct xinpcb and friends word-size independent.
Replace size_t members with ksize_t (uint64_t) and pointer members
(never used as pointers in userspace, but instead as unique
idenitifiers) with kvaddr_t (uint64_t). This makes the structs
identical between 32-bit and 64-bit ABIs.

On 64-bit bit systems, the ABI is maintained. On 32-bit systems,
this is an ABI breaking change. The ABI of most of these structs
was previously broken in r315662.  This also imposes a small API
change on userspace consumers who must handle kernel pointers
becoming virtual addresses.

7551d83c35 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

7168fac388 Hide struct socket and struct unpcb from the userland.
Violators may define _WANT_SOCKET and _WANT_UNPCB respectively and
are not guaranteed for stability of the structures.  The violators
list is the the usual one: libprocstat(3) and netstat(1) internally
and lsof in ports.

In struct xunpcb remove the inclusion of kernel structure and add
a bunch of spare fields.  The xsocket already has socket not included,
but add there spares as well.  Embed xsockbuf into xsocket.

Sort declarations in sys/socketvar.h to separate kernel only from
userland available ones.

3a5c9aaf2b Hide struct inpcb, struct tcpcb from the userland.
This is a painful change, but it is needed.  On the one hand, we avoid
modifying them, and this slows down some ideas, on the other hand we still
eventually modify them and tools like netstat(1) never work on next version of
FreeBSD.  We maintain a ton of spares in them, and we already got some ifdef
hell at the end of tcpcb.

Details:
- Hide struct inpcb, struct tcpcb under _KERNEL || _WANT_FOO.
- Make struct xinpcb, struct xtcpcb pure API structures, not including
  kernel structures inpcb and tcpcb inside.  Export into these structures
  the fields from inpcb and tcpcb that are known to be used, and put there
  a ton of spare space.
- Make kernel and userland utilities compilable after these changes.
- Bump __FreeBSD_version.

6e8e43ab0e This patch fixes two bugs:
* sctp46, tcp46, and udp46 sockets are displayed as such and not as
  sctp4 6, tcp4 6, udp4 6. This bug was introduced in
  http://svnweb.freebsd.org/base?view=revision&revision=187915
* For SCTP sockets, the the -4 and -6 flags are honoured as much as
  possible. This means IPv4 sockets are handled correctly,  IPv6
  sockets are displayed as sctp46, since it is currently not possible
  to distinguish between sctp6 and sctp46.

67d5f1a727 - Updated TOE support in the kernel.
- Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs.
  These are available as t3_tom and t4_tom modules that augment cxgb(4)
  and cxgbe(4) respectively.  The cxgb/cxgbe drivers continue to work as
  usual with or without these extra features.

- iWARP driver for Terminator 3 ASIC (kernel verbs).  T4 iWARP in the
  works and will follow soon.

Build-tested with make universe.

30s overview
============
What interfaces support TCP offload?  Look for TOE4 and/or TOE6 in the
capabilities of an interface:
# ifconfig -m | grep TOE

Enable/disable TCP offload on an interface (just like any other ifnet
capability):
# ifconfig cxgbe0 toe
# ifconfig cxgbe0 -toe

Which connections are offloaded?  Look for toe4 and/or toe6 in the
output of netstat and sockstat:
# netstat -np tcp | grep toe
# sockstat -46c | grep toe
