7735aeb9bb Add support for WCCPv2. It should be enablem manually using link2
ifconfig(8) flag since header for version 2 is the same but IP payload
is prepended with additional 4-bytes field.

73d7ddbc56 Sync with NetBSD:
if_gre.c rev.1.41-1.49

 o Spell output with two ts.
 o Remove assigned-to but not used variable.
 o fix grammatical error in a diagnostic message.
 o u_short -> u_int16_t.
 o gi_len is ip_len, so it has to be network byteorder.

if_gre.h rev.1.11-1.13

 o prototype must not have variable name.
 o u_short -> u_int16_t.
 o Spell address with two d's.

ip_gre.c rev.1.22-1.29

 o KNF - return is not a function.
 o The "osrc" variable in gre_mobile_input() is only ever set but not
   referenced; remove it.
 o correct (false) assumptions on mbuf chain.  not sure if it really helps, but
   anyways, it is necessary to perform m_pullup.
 o correct arg to m_pullup (need to count IP header size as well).
 o remove redundant adjustment of m->m_pkthdr.len.
 o clear m_flags just for safety.
 o tabify.
 o u_short -> u_int16_t.

437ffe1823 o eliminate widespread on-stack mbuf use for bpf by introducing
a new bpf_mtap2 routine that does the right thing for an mbuf
  and a variable-length chunk of data that should be prepended.
o while we're sweeping the drivers, use u_int32_t uniformly when
  when prepending the address family (several places were assuming
  sizeof(int) was 4)
o return M_ASSERTVALID to BPF_MTAP* now that all stack-allocated
  mbufs have been eliminated; this may better be moved to the bpf
  routines

f16770ae7e Fix a bug whereby the physical endpoints of a gre(4) tunnel would not
be printed, if the module were loaded into a kernel which had INET6 enabled.

The gre(4) driver does not use INET6, nor is it specified for IPv6. The
tunnel_status() function in ifconfig(8) is somewhat overzealous and assumes
that all tunnel interfaces speak KAME ifioctls.

This fix follows the path of least resistance, by teaching gre(4) about
the two KAME ifioctls concerned.

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

3c6b084e96 Finish driving a stake through the heart of netns and the associated
ifdefs scattered around the place - its dead Jim!

The SMB stuff had stolen AF_NS, make it official.

6fc32a2495 network interface and link layer changes:
o on input don't strip the Ethernet header from packets
o input packet handling is now done with if_input
o track changes to ether_ifattach/ether_ifdetach API
o track changes to bpf tapping
o call ether_ioctl for default handling of ioctl's
o use constants from net/ethernet.h where possible

5d84645305 Replace aux mbufs with packet tags:
o instead of a list of mbufs use a list of m_tag structures a la openbsd
o for netgraph et. al. extend the stock openbsd m_tag to include a 32-bit
  ABI/module number cookie
o for openbsd compatibility define a well-known cookie MTAG_ABI_COMPAT and
  use this in defining openbsd-compatible m_tag_find and m_tag_get routines
o rewrite KAME use of aux mbufs in terms of packet tags
o eliminate the most heavily used aux mbufs by adding an additional struct
  inpcb parameter to ip_output and ip6_output to allow the IPsec code to
  locate the security policy to apply to outbound packets
o bump __FreeBSD_version so code can be conditionalized
o fixup ipfilter's call to ip_output based on __FreeBSD_version

Removed unused includes.

Removed used includes of <sys/queue.h> and <sys/time.h>, since these are
standard pollution (especially the latter).
