[PATCH net-next 0/4] rxrpc: Miscellaneous changes

[David Howells <dhowells@redhat.com>]

Here are some miscellaneous changes for rxrpc:

 (1) Use consume_skb() rather than kfree_skb_reason().

 (2) Fix unnecessary waking when poking and already-poked call.

 (3) Add ack.rwind to the rxrpc_tx_ack tracepoint as this indicates how
     many incoming DATA packets we're telling the peer that we are
     currently willing to accept on this call.

 (4) Reduce duplicate ACK transmission.  We send ACKs to let the peer know
     that we're increasing the receive window (ack.rwind) as we consume
     packets locally.  Normal ACK transmission is triggered in three places
     and that leads to duplicates being sent.

The patches are tagged here:
