Support the "dsa" kind of rtnl_link_ops exported by the kernel, and
export reads/writes to IFLA_DSA_MASTER.
Examples:
$ ip link set swp0 type dsa conduit eth1
$ ip -d link show dev swp0
(...)
dsa conduit eth0
$ ip -d -j link show swp0
[
{
"link": "eth1",
"linkinfo": {
"info_kind": "dsa",
"info_data": {
"conduit": "eth1"
}
},
}
]
Note that by construction and as shown in the example, the IFLA_LINK
reported by a DSA user port is identical to what is reported through
IFLA_DSA_MASTER. However IFLA_LINK is not writable, and overloading its
meaning to make it writable would clash with other users of IFLA_LINK
(vlan etc) for which writing this property does not make sense.
