Subject: [PATCH net-next 0/5] RDS: TCP: Enable mprds for rds-tcp

The third, and final, installment for mprds-tcp changes.

In Patch 3 of this set, if the transport support t_mp_capable, 
we hash outgoing traffic across multiple paths.  Additionally, even if 
the transport is MP capable, we may be peering with some node that does
not support mprds, or supports a different number of paths. This
necessitates RDS control plane changes so that both peers agree
on the number of paths to be used for the rds-tcp connection.
Patch 3 implements all these changes, which are documented in patch 5
of the series.

Patch 1 of this series is a bug fix for a race-condition
that has always existed, but is now more easily encountered with mprds. 
Patch 2 is code refactoring. Patches 4 and 5 are Documentation updates.

Sowmini Varadhan (5):
  RDS: TCP: avoid bad page reference in rds_tcp_listen_data_ready
  RDS: TCP: Reduce code duplication in rds_tcp_reset_callbacks()
  RDS: TCP: Enable multipath RDS for TCP
  Documentation: RDS: updates for SO_RDS_TRANSPORT socket option
  Documentation: RDS: Document Multipath RDS (mprds)
