This patch makes CAN_CTRLMODE_FD_NON_ISO netlink feature configurable.
During the CAN FD standardization process within the ISO it turned out that
the failure detection capability has to be improved.
The CAN in Automation organization (CiA) defined the already implemented CAN
FD controllers as 'non-ISO' and the upcoming improved CAN FD controllers as
'ISO' compliant. See at http://www.can-cia.com/index.php?id=1937
Starting with the - currently non-ISO - driver for M_CAN v3.0.1 introduced in
Linux 3.18 this bit needs to be propagated to userspace. In future drivers this
bit will become configurable depending on the CAN FD controllers capabilities.

"ip addr show up" would exclude the interface (link), but include the
addresses of down interfaces (which looked like they where indented
under a different interface). This fixes the filtering.

This change allows to exec some cmd on each
named netns (except default) by specifying '-all' option:
# ip -all netns exec ip link
Each command executes synchronously.
Exit status is not considered, so there might be a case
that some CMD can fail on some netns but success on the other.
EXAMPLES:
1) Show link info on all netns:
$ ip -all netns exec ip link
netns: test_net
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN mode DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
4: tap0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 500
link/ether 1a:19:6f:25:eb:85 brd ff:ff:ff:ff:ff:ff
netns: home0
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN mode DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
4: tap0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 500
link/ether ea:1a:59:40:d3:29 brd ff:ff:ff:ff:ff:ff
netns: lan0
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN mode DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
4: tap0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 500
link/ether ce:49:d5:46:81:ea brd ff:ff:ff:ff:ff:ff
2) Set UP tap0 device for the all netns:
$ ip -all netns exec ip link set dev tap0 up
netns: test_net
netns: home0
netns: lan0

Added two tests which checks the following fixed issues:
1) Bug when not possible add new virtual interface via:
$ ip link add dev XXX type
It was fixed a few releases ago.
2) Crash on older kernels when VF rate info does not exist:
$ ip link show
Used dump file from William Dauchy <william@gandi.net>:
testsuite/tests/ip/link/dev_wo_vf_rate.nl
So 'ip link show' replaced by 'ip -d monitor file ...' which does
the same thing.
Also added new func in testsuite/lib/generic.sh to gen new random dev name.
Added 'clean' dependency on running all tests.

As inet dgram sockets (udp, raw) can call connect(...) - they
might be set in ESTABLISHED state. So keep the original behaviour of
'ss' which filtered them by ESTABLISHED state by default. So:
$ ss -u
or
$ ss -w
Will show only ESTABLISHED UDP sockets by default.

When HAVE_SETNS is not set, iproute2 provides a local implementation of this
function based on __NR_setns.
This macro is defined in sys/syscall.h, which was not included, thus the local
implementation always returned -1.

When 'ss' prints UDP sockets info together with RAW sockets
e.g.:
$ ss -a
then UDP sockets are resolved as "ipproto-xxx".
It was caused that dg_proto was set after printing UDP
socket info from netlink. So fixed issue by moving
setting dg_proto before printing info from Netlink.

This patch fixes some filtering combinations issues which does not
work on the 'master' version:
$ ss -4
shows inet & unix sockets, instead of only inet sockets
$ ss -u
needs to specify 'state closed'
$ ss src unix:*X11*
needs to specify '-x' shortcut for UNIX family
$ ss -A all
shows only sockets with established states
There might some other issues which was not observed.
Also changed logic for calculating families, socket types and
states filtering. I think that this version is a little simpler
one. Now there are 2 predefined default tables which describes
the following maping:
family -> (states, dbs)
db -> (states, families)

Sometimes, it is more convenient to get only one specific nested attribute by
type. For example for IFLA_AF_SPEC where type is address family (AF_INET6).
So add this helper for this purpose.

v2:
Resending now that the dust has cleared in 3.18 on "self" vs. hwmode debate for
brport settings. learning_sync is now set/cleared using "self" qualifier on
brport.
v1:
Add 'learned_sync' flag to turn on/off syncing of learned MAC addresses from
offload device to bridge's FDB. Flag is be set/cleared on offload device port
using "self" qualifier:
$ sudo bridge link set dev swp1 learning_sync on self
$ bridge -d link show dev swp1
2: swp1 state UNKNOWN : <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br0 state forwarding priority 32 cost 2
hairpin off guard off root_block off fastleave off learning off flood off
2: swp1 state UNKNOWN : <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br0
learning on learning_sync on
Adds new IFLA_BRPORT_LEARNED_SYNCED attribute for IFLA_PROTINFO on the SELF
brport.

Currently self is set internally only if hwmode is set.
This makes it necessary for the hw to have a mode.
There is no hwmode really required to go to hardware. So, introduce
self for anybody who wants to target hardware.
v1 -> v2
- fix a few bugs. Initialize flags to zero: this was required to
keep the current behaviour unchanged.
v2 -> v3
