yamt ffebedd625 factor out receive side tcp/udp checksum handling code so that they
can be used by eg. packet filters.

reviewed by Christos Zoulas on tech-net@.
(slightly tweaked since then to make tcp and udp similar.)

thorpej 7994b6f95e Don't perform checksums on loopback interfaces. They can be reenabled with
the net.inet.*.do_loopback_cksum sysctl.

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

thorpej 10c252ba47 Changes to allow the IPv4 and IPv6 layers to align headers themseves,
as necessary:
* Implement a new mbuf utility routine, m_copyup(), is is like
  m_pullup(), except that it always prepends and copies, rather
  than only doing so if the desired length is larger than m->m_len.
  m_copyup() also allows an offset into the destination mbuf, which
  allows space for packet headers, in the forwarding case.
* Add *_HDR_ALIGNED_P() macros for IP, IPv6, ICMP, and IGMP.  These
  macros expand to 1 if __NO_STRICT_ALIGNMENT is defined, so that
  architectures which do not have strict alignment constraints don't
  pay for the test or visit the new align-if-needed path.
* Use the new macros to check if a header needs to be aligned, or to
  assert that it already is, as appropriate.

Note: This code is still somewhat experimental.  However, the new
code path won't be visited if individual device drivers continue
to guarantee that packets are delivered to layer 3 already properly
aligned (which are rules that are already in use).

bouyer f86517a031 Update protocoles and interfaces stats counters to 64bit.
RTM_IFINFO is now 0xf, 0xe is RTM_OIFINFO which returns the old (if_msghdr14)
struct with 32bit counters (binary compat, conditioned on COMPAT_14).
Same for sysctl: node 3 is renamed NET_RT_OIFLIST, NET_RT_IFLIST is now node 4.
Change rt_msg1() to add an mbuf to the mbuf chain instead of just panic()
when the message is larger than MHLEN.

mycroft 49d52c9b1c Pass a proc pointer down to the usrreq and pcbbind functions for PRU_ATTACH, PRU_BIND and
PRU_CONTROL.  The usrreq interface really needs to be split up, but this will have to wait.
Remove SS_PRIV completely.

cgd dfad729a16 make netinet work on systems where pointers and longs are 64 bits
(like the alpha).  Biggest problem: IP headers were overlayed with
structure which included pointers, and which therefore didn't overlay
properly on 64-bit machines.  Solution: instead of threading pointers
through IP header overlays, add a "queue element" structure to do
the threading, and point it at the ip headers.

mycroft 6897f39ae9 Various cleanup, including:
* Convert several data structures to use queue.h.
* Split in_pcbnotify() into two parts; one for notifying a specific PCB, and
one for notifying all PCBs for a particular foreign address.
