Subject: [PATCH net-next v1 0/7] net/rds: RDS-TCP protocol and extension improvements

From: Allison Henderson <allison.henderson@...cle.com>

Hi all,

This is subset 3 of the larger RDS-TCP patch series I posted last
Oct.  The greater series aims to correct multiple rds-tcp issues that
can cause dropped or out of sequence messages.  I've broken it down into
smaller sets to make reviews more manageable.

In this set, we introduce extension headers for byte accounting
and fix several RDS/TCP protocol issues including message preservation
during connection transitions and multipath lane handling.

The entire set can be viewed in the rfc here:
https://lore.kernel.org/netdev/20251022191715.157755-1-achender@kernel.org/

Questions, comments, flames appreciated!
Thanks!
Allison

  net/rds: Encode cp_index in TCP source port
  net/rds: rds_tcp_conn_path_shutdown must not discard messages
  net/rds: Kick-start TCP receiver after accept
  net/rds: Use the first lane until RDS_EXTHDR_NPATHS arrives
  net/rds: Trigger rds_send_ping() more than once
