tipc: add link get/dump to new netlink api
Add TIPC_NL_LINK_GET command to the new tipc netlink API.
This command supports dumping all information about all links
(including the broadcast link) or getting all information about a
specific link (not the broadcast link).
The information about a link includes name, transmission info,
properties and link statistics.
As the tipc broadcast link is special we unfortunately have to treat
it specially. It is a deliberate decision not to abstract the
broadcast link on this (API) level.
Netlink logical layout of link response message:
-> port
-> name
-> MTU
-> RX
-> TX
-> up flag
-> active flag
-> properties
-> priority
-> tolerance
-> window
-> statistics
-> rx_info
-> rx_fragments
-> rx_fragmented
-> rx_bundles
-> rx_bundled
-> tx_info
-> tx_fragments
-> tx_fragmented
-> tx_bundles

-> msg_len_tot
-> msg_len_p0

-> msg_len_p2
