tipc: add bearer disable/enable to new netlink api
A new netlink API for tipc that can disable or enable a tipc bearer.
The new API is separated from the old API because of a bug in the
user space client (tipc-config). The problem is that older versions
of tipc-config has a very low receive limit and adding commands to
the legacy genl_opts struct causes the ctrl_getfamily() response
message to grow, subsequently breaking the tool.
The new API utilizes netlink policies for input validation. Where the
top-level netlink attributes are tipc-logical entities, like bearer.
The top level entities then contain nested attributes. In this case
a name, nested link properties and a domain.
Netlink commands implemented in this patch:
TIPC_NL_BEARER_ENABLE
TIPC_NL_BEARER_DISABLE
Netlink logical layout of bearer enable message:
-> bearer
-> name
[ -> domain ]
[
-> properties
-> priority
]
Netlink logical layout of bearer disable message:
-> bearer
-> name
