[PATCH net-next 0/9] RDS:TCP data structure changes for multipath support

[Sowmini Varadhan <sowmini.varadhan@oracle.com>]

The second installment of changes to enable multipath support in
RDS-TCP. This series implements the changes in rds-tcp so that the 
rds_conn_path has a pointer to the rds_tcp_connection in cp_transport_data.
Struct rds_tcp_connection keeps track of the inet_sk per path in
t_sock. The ->sk_user_data in turn is a pointer to the rds_conn_path.
With this set of changes, rds_tcp has the needed plumbing to handle
multiple paths(socket) per rds_connection.

Sowmini Varadhan (9):
  RDS: Rework path specific indirections
  RDS: TCP: Remove dead logic around c_passive in rds-tcp
  RDS: TCP: Make rds_tcp_connection track the rds_conn_path
  RDS: TCP: Refactor connection destruction to handle multiple paths
  RDS: TCP: make ->sk_user_data point to a rds_conn_path
  RDS: TCP: make receive path use the rds_conn_path
  RDS: TCP: Hooks to set up a single connection path
  RDS: TCP: Simplify reconnect to avoid duelling reconnnect attempts
  RDS: Do not send a pong to an incoming ping with 0 src port
