[PATCH net-next 0/7] rxrpc: More fixes and adjustments

[David Howells <dhowells@redhat.com>]

This set of patches contains some more fixes and adjustments:

 (1) Actually display the retransmission indication previously added to the
     tx_data trace.

 (2) Switch to Congestion Avoidance mode properly at cwnd==ssthresh rather
     than relying on detection during an overshoot and correction.

 (3) Reduce ssthresh to the peer's declared receive window.

 (4) The offset field in rxrpc_skb_priv can be dispensed with and the error
     field is no longer used.  Get rid of them.

 (5) Keep the call timeouts as ktimes rather than jiffies to make it easier
     to deal with RTT-based timeout values in future.  Rounding to jiffies
     is still necessary when the system timer is set.

 (6) Fix the call timer handling to avoid retriggering of expired timeout
     actions.
