Merge branch 'tipc-next'
Erik Hugne says:
====================
tipc: add support for link state subscriptions
Low level topology information like TIPC link up/down is useful for
applications like teamd to make smarter failover decisions in a
HA cluster environment. Fetching logical link names through an ioctl
may hurt the eyes of some. Suggestions for a more elegant way of doing
this would be appreciated in that case. :)
v2:
-Properly based on net-next
-Off-list comments from Billie Alsup:
-Add a string length parameter to tipc_node_get_linkname
-Use TIPC_MAX_LINK_NAME definition instead of hardcoded
value in tipc_sioc_ln_req linkname
====================
