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

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

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.

This permits to selectively enable explicit congestion notification via
the routing table.
If this ecn feature is not set, the kernel will use the tcp_ecn sysctl
to decide wheter to use ECN when establising a TCP connection.
At the time of this writing, the kernel supports ecn and allfrags, but
allfrags is of dubious value and not implemented here.
Example:
ip route change 192.168.2.0/24 dev eth0 features ecn

-iec print human readable rates in IEC units (ie. 1K = 1024).

As 'ip' util will share the same netns from the caller
process then we can just look at /proc/self/.. to show

o "min_tx_rate" option has been added for minimum Tx rate. Hence, for
consistent naming, "max_tx_rate" option has been introduced for maximum
Tx rate.
o Change in v2: "rate" can be used along with "max_tx_rate".
When both are specified, "max_tx_rate" should override.
o Change in v3:
* IFLA_VF_RATE: When IFLA_VF_RATE is used, and user has given only one of
min_tx_rate or max_tx_rate, reading of previous rate limits is done in
userspace instead of in kernel space before ndo_set_vf_rate.
* IFLA_VF_TX_RATE: When IFLA_VF_TX_RATE is used, min_tx_rate is always read
in kernel space. This takes care of below scenarios:
(1) when old tool sends "rate" but kernel is new (expects min and max)
(2) when new tool sends only "rate" but kernel is old (expects only "rate")
o Change in v4 as suggested by Stephen Hemminger:
* As per iproute policy, input and output formats should match. Changing display
of max_tx_rate and min_tx_rate options accordingly.
