a way to retrive it
NOTE: Due to restructuring, the merges didn't apply cleanly; the resulting
change is almost identical to what went into stable/11, but in some cases in
different locations.
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.

- Make lagg protos a enum.
- When reconfiguring protocol on a lagg, first set it to LAGG_PROTO_NONE,
then drop lock, run the attach routines, and then set it to specific
proto. This removes tons of WITNESS warnings.
- Make lagg protocol attach handlers not failing and allocate memory
with M_WAITOK.
- Virtualize lagg(4) cloner. This change fixes a panic when tearing down
if_lagg(4) interfaces which were cloned in a vnet jail.
Sysctl nodes which are dynamically generated for each cloned interface
(net.link.lagg.N.*) have been removed, and use_flowid and flowid_shift
ifconfig(8) parameters have been added instead. Flags and per-interface
statistics counters are displayed in "ifconfig -v".
- Separate option handling from SIOC[SG]LAGG to SIOC[SG]LAGGOPTS for
backward compatibility with old ifconfig(8).
- Move L2 addr configuration for the primary port to a taskqueue. This fixes
LOR of softc rmlock in iflladdr_event handlers.
- Call if_delmulti_ifma() after LACP_UNLOCK(). This fixes another LOR.
- Fix a panic in lacp_transit_expire().
- Fix a panic in lagg_input() upon shutting down a port.
- Use printb() for boolean flags in ro_opts and actor_state for LACP.
- Fix lladdr configuration which could prevent LACP mode from working.
- Fix LORs when a laggport interface has an IPv6 LLA.

Add support for reading i2c SFP/SFP+ data from NIC driver and
presenting most interesting fields via ifconfig -v.
This version supports Intel ixgbe driver only.
Tested on: Cisco,Intel,Mellanox,ModuleTech,Molex transceivers
* Add new net/sff8436.h containing constants used to access
QSFP+ data via i2c inteface. These constants has been taken
from SFF-8436 "QSFP+ 10 Gbs 4X PLUGGABLE TRANSCEIVER" standard
rev 4.8.
* Add support for printing QSFP+ information from 40G NICs
such as Chelsio T5.
Example:
cxl1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=ec07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,.....>
ether 00:07:43:28:ad:08
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet 40Gbase-LR4 <full-duplex>
status: active
plugged: QSFP+ 40GBASE-LR4 (MPO Parallel Optic)
vendor: OEM PN: OP-QSFP-40G-LR4 SN: 20140318001 DATE: 2014-03-18
module temperature: 64.06 C voltage: 3.26 Volts

because a link where looped back NS messages are permanently observed
does not work with either NDP or ARP for IPv4.

Overhaul if_gre(4).
Split it into two modules: if_gre(4) for GRE encapsulation and
if_me(4) for minimal encapsulation within IP.
gre(4) changes:
* convert to if_transmit;
* rework locking: protect access to softc with rmlock,
protect from concurrent ioctls with sx lock;
* correct interface accounting for outgoing datagramms (count only payload size);
* implement generic support for using IPv6 as delivery header;
* make implementation conform to the RFC 2784 and partially to RFC 2890;
* add support for GRE checksums - calculate for outgoing datagramms and check
for inconming datagramms;
* add support for sending sequence number in GRE header;
* remove support of cached routes. This fixes problem, when gre(4) doesn't
work at system startup. But this also removes support for having tunnels with
the same addresses for inner and outer header.
* deprecate support for various GREXXX ioctls, that doesn't used in FreeBSD.
Use our standard ioctls for tunnels.
me(4):
* implementation conform to RFC 2004;
* use if_transmit;
* use the same locking model as gre(4);

Provide a working example line for an interface with 1 address running
with CARP.
Currently, we've got a problem that interface isn't IFF_UP at the time
we assign it a redundant address, and the latter gets stuck in INIT state.
Additional SIOCSIFFLAGS from ifconfig(8) kicks it to a working state.
A proper fix is kernel side and appeared to be non-trivial, not to be
checked in before 10.0-RELEASE.

KAME-specific sin6_scope_id handling routine from each userland utility:
sin6.sin6_scope_id = ntohs(*(u_int16_t *)&sin6.sin6_addr.s6_addr[2]);
This behavior can be controlled by net.inet6.ip6.deembed_scopeid. This is
set to 1 by default (sin6_scope_id will be filled 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
