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 -> tx_bundled -> msg_prof_tot -> msg_len_cnt -> msg_len_tot -> msg_len_p0 -> msg_len_p1 -> msg_len_p2 -> msg_len_p3 -> msg_len_p4 -> msg_len_p5 -> msg_len_p6 -> rx_states -> rx_probes -> rx_nacks -> rx_deferred -> tx_states -> tx_probes -> tx_nacks -> tx_acks -> retransmitted -> duplicates -> link_congs -> max_queue -> avg_queue Signed-off-by: Richard Alpe <richard.alpe@ericsson.com> Reviewed-by: Erik Hugne <erik.hugne@ericsson.com> Reviewed-by: Jon Maloy <jon.maloy@ericsson.com> Acked-by: Ying Xue <ying.xue@windriver.com> Signed-off-by: David S.
