4204224162 Finish removing FDDI and tokenring media support.
This fixes media display for 802.11 wireless devices.

Software outside the base system that uses these media types and
defines should use #ifdef IFM_FDDI or IFM_TOKEN to include or remove
support.

47528c67ef Make lagg creation more fault tolerant
- Warn, don't exit, when SIOCSLAGGPORT returns an error.

When we exit with an error during lagg creation, a single
failed NIC (which no longer attaches) can prevent lagg
creation and other configuration, such as adding an IPv4
address, and thus leave a machine unreachable.

- Preserve non-EEXISTS errors for exit status from SIOCSLAGGPORT,
  in case scripts are looking for it. Hopefully this can be
  extended if other parts of ifconfig can allow a "soft" failure.

- Improve the warning message to mention what lagg and what
  member are problematic.

f137973487 Allow to specify PCP on packets not belonging to any VLAN.
According to 802.1Q-2014, VLAN tagged packets with VLAN id 0 should be
considered as untagged, and only PCP and DEI values from the VLAN tag
are meaningful.  See for instance
https://www.cisco.com/c/en/us/td/docs/switches/connectedgrid/cg-switch-sw-master/software/configuration/guide/vlan0/b_vlan_0.html.

Make it possible to specify PCP value for outgoing packets on an
ethernet interface.  When PCP is supplied, the tag is appended, VLAN
id set to 0, and PCP is filled by the supplied value.  The code to do
VLAN tag encapsulation is refactored from the if_vlan.c and moved into
if_ethersubr.c.

Drivers might have issues with filtering VID 0 packets on
receive.  This bug should be fixed for each driver.

3cf8254f1e Add a place for a driver to report rx timestamps in nanoseconds from
boot for the received packets.

The rcv_tstmp field overlaps the place of Ln header length indicators,
not used by received packets.  The basic pkthdr rearrangement change
in sys/mbuf.h was provided by gallatin.

There are two accompanying M_ flags: M_TSTMP means that there is the
timestamp (and it was generated by hardware).

Another flag M_TSTMP_HPREC indicates that the timestamp is
high-precision.  Practically M_TSTMP_HPREC means that hardware
provided additional precision comparing with the stamps when the flag
is not set.  E.g., for ConnectX all packets are stamped by hardware
when PCIe transaction to write out the completion descriptor is
performed, but PTP packet are stamped on port.  For Intel cards, when
PTP assist is enabled, only PTP packets are stamped in the limited
number of registers, so if Intel cards ever start support this
mechanism, they would always set M_TSTMP | M_TSTMP_HPREC if hardware
timestamp is present for the given packet.

Add IFCAP_HWRXTSTMP interface capability to indicate the support for
hardware rx timestamping, and ifconfig(8) command to toggle it.

ddae57504b Persistently store NIC's hardware MAC address, and add a way to retrive it
The MAC address reported by `ifconfig ${nic} ether' does not always match
the address in the hardware, as reported by the driver during attach. In
particular, NICs which are components of a lagg(4) interface all report the
same MAC.

When attaching, the NIC driver passes the MAC address it read from the
hardware as an argument to ether_ifattach(). Keep a second copy of it, and
create ioctl(SIOCGHWADDR) to return it. Teach `ifconfig' to report it along
with the active MAC address.

fcf596178b Merge projects/ipsec into head/.
Small summary
 -------------

o Almost all IPsec releated code was moved into sys/netipsec.
o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel
  option IPSEC_SUPPORT added. It enables support for loading
  and unloading of ipsec.ko and tcpmd5.ko kernel modules.
o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by
  default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type
  support was removed. Added TCP/UDP checksum handling for
  inbound packets that were decapsulated by transport mode SAs.
  setkey(8) modified to show run-time NAT-T configuration of SA.
o New network pseudo interface if_ipsec(4) added. For now it is
  build as part of ipsec.ko module (or with IPSEC kernel).
  It implements IPsec virtual tunnels to create route-based VPNs.
o The network stack now invokes IPsec functions using special
  methods. The only one header file <netipsec/ipsec_support.h>
  should be included to declare all the needed things to work
  with IPsec.
o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed.
  Now these protocols are handled directly via IPsec methods.
o TCP_SIGNATURE support was reworked to be more close to RFC.
o PF_KEY SADB was reworked:
  - now all security associations stored in the single SPI namespace,
    and all SAs MUST have unique SPI.
  - several hash tables added to speed up lookups in SADB.
  - SADB now uses rmlock to protect access, and concurrent threads
    can do SA lookups in the same time.
  - many PF_KEY message handlers were reworked to reflect changes
    in SADB.
  - SADB_UPDATE message was extended to support new PF_KEY headers:
    SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They
    can be used by IKE daemon to change SA addresses.
o ipsecrequest and secpolicy structures were cardinally changed to
  avoid locking protection for ipsecrequest. Now we support
  only limited number (4) of bundled SAs, but they are supported
  for both INET and INET6.
o INPCB security policy cache was introduced. Each PCB now caches
  used security policies to avoid SP lookup for each packet.
o For inbound security policies added the mode, when the kernel does
  check for full history of applied IPsec transforms.
o References counting rules for security policies and security
  associations were changed. The proper SA locking added into xform
  code.
o xform code was also changed. Now it is possible to unregister xforms.
  tdb_xxx structures were changed and renamed to reflect changes in
  SADB/SPDB, and changed rules for locking and refcounting.

f3e7afe2d7 Implement kernel support for hardware rate limited sockets.
- Add RATELIMIT kernel configuration keyword which must be set to
enable the new functionality.

- Add support for hardware driven, Receive Side Scaling, RSS aware, rate
limited sendqueues and expose the functionality through the already
established SO_MAX_PACING_RATE setsockopt(). The API support rates in
the range from 1 to 4Gbytes/s which are suitable for regular TCP and
UDP streams. The setsockopt(2) manual page has been updated.

- Add rate limit function callback API to "struct ifnet" which supports
the following operations: if_snd_tag_alloc(), if_snd_tag_modify(),
if_snd_tag_query() and if_snd_tag_free().

- Add support to ifconfig to view, set and clear the IFCAP_TXRTLMT
flag, which tells if a network driver supports rate limiting or not.

- This patch also adds support for rate limiting through VLAN and LAGG
intermediate network devices.

- How rate limiting works:

1) The userspace application calls setsockopt() after accepting or
making a new connection to set the rate which is then stored in the
socket structure in the kernel. Later on when packets are transmitted
a check is made in the transmit path for rate changes. A rate change
implies a non-blocking ifp->if_snd_tag_alloc() call will be made to the
destination network interface, which then sets up a custom sendqueue
with the given rate limitation parameter. A "struct m_snd_tag" pointer is
returned which serves as a "snd_tag" hint in the m_pkthdr for the
subsequently transmitted mbufs.

2) When the network driver sees the "m->m_pkthdr.snd_tag" different
from NULL, it will move the packets into a designated rate limited sendqueue
given by the snd_tag pointer. It is up to the individual drivers how the rate
limited traffic will be rate limited.

3) Route changes are detected by the NIC drivers in the ifp->if_transmit()
routine when the ifnet pointer in the incoming snd_tag mismatches the
one of the network interface. The network adapter frees the mbuf and
returns EAGAIN which causes the ip_output() to release and clear the send
tag. Upon next ip_output() a new "snd_tag" will be tried allocated.

4) When the PCB is detached the custom sendqueue will be released by a
non-blocking ifp->if_snd_tag_free() call to the currently bound network
interface.

* VHT20, VHT40 and VHT80 channel configuration / population
* Parses vht channel specifications (eg ifconfig wlan0 create wlandev athp0 wlanmode monitor channel 36:vht/80)
* Configuration of VHT, VHT40, VHT80, VHT80+80, VHT160 channel

  not yet sure how to support/populate VHT80+80 channels.
* No, I won't update the manpage until this is "more done", lest someone
  tries using vht and gets upset with me.
* No, I won't commit the regulatory database I'm testing with, so you'll
  just end up with no VHT channels ever populated.  Which is good, as there
  isn't an 11ac driver in-tree yet to try it with.

2ccbbd06d2 Add support to priority code point (PCP) that is an 3-bit field
which refers to IEEE 802.1p class of service and maps to the frame
priority level.

Values in order of priority are: 1 (Background (lowest)),
0 (Best effort (default)), 2 (Excellent effort),
3 (Critical applications), 4 (Video, < 100ms latency),
5 (Video, < 10ms latency), 6 (Internetwork control) and
7 (Network control (highest)).

Example of usage:
root# ifconfig em0.1 create
root# ifconfig em0.1 vlanpcp 3

Note:
The review D801 includes the pf(4) part, but as discussed with kristof,
we won't commit the pf(4) bits for now.
The credits of the original code is from rwatson.

776db16a76 Address feedback from hrs@ re: r301059 (ifconfig subnet mask)
- Use NI_MAXHOST to size buffers for getnameinfo()
- remove non-standard 'full' inet6 address printing
- remove 'no scope' option
- use strchr(3) to optimize replacing separator character in lladdrs

7c2aa74437 ifconfig(8) now supports some output formatting options
specified by the -f flag or IFCONFIG_FORMAT environment variable, the user
can request that inet4 subnet masks be printed in CIDR or dotted-quad
notation, in addition to the traditional hex output.
inet6 prefixes can be printed in CIDR as well.

For more documentation see the ifconfig(8) man page.
