This patch adds support to specify 'master' keyword,
to target a bridge link command explicitly to the software
bridge driver.
Adds self/master keywords to usage and man page
v2:
fix usage to say (self and master) and not (self or master)

The existing behaviour forces one to memorize the integer constants for
STP port states.
# bridge link set dev dummy0 state 3
This patch makes it possible to use the lowercased port state name.
# bridge link set dev dummy0 state forwarding

The kernel now provides ids for peer netns. This patch implements a new command
'set' to assign an id.
When netns are listed, if an id is assigned, it is now displayed.
Example:
$ ip netns add foo
$ ip netns set foo 1
$ ip netns
foo (id: 1)
init_net

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

2) Set UP tap0 device for the all netns:

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

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
