One option is required for bearer set and bearer get.

Align with upstream kernel.

Before this patch both addmdb and delmdb events were printed the same,
now we'll get a "Deleted" string in front when delmdb is received.
Before:
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1
(monitor) dev br0 port eth3 grp 239.0.0.1 temp
$ bridge mdb del dev br0 port eth3 grp 239.0.0.1
(monitor) dev br0 port eth3 grp 239.0.0.1 temp
^^ No way to differentiate between both events.

After:
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1
(monitor) dev br0 port eth3 grp 239.0.0.1 temp
$ bridge mdb del dev br0 port eth3 grp 239.0.0.1
(monitor) Deleted dev br0 port eth3 grp 239.0.0.1 temp

This patch adds support to set and display protodown on a switch port. The
switch driver can handle this error state by doing a phys down on the port.

One example user space application setting this flag is a multi-chassis
LAG application to handle split-brain situation on peer-link failure.

Example:
root@net-next:~# ip link set eth1 protodown on
root@net-next:~/iproute2# ip link show eth1
4: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 52:54:00:12:35:01 brd ff:ff:ff:ff:ff:ff protodown on
root@net-next:~/iproute2# ip link set eth1 protodown off
root@net-next:~/iproute2# ip link show eth1
4: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

There is no special reason to use the secure version of getenv, thus let's

After commit 8250bc9f ("ss: Unify inet sockets output") raw sockets
are displayed as udp because dgram_show_line() is used for both and
thus IPPROTO_UDP is used for both so proto_name() returns "udp".
Fix this by checking dg_proto which is set according to the caller of
dgram_show_line().
