[PATCH net-next 02/15] rxrpc: Don't send an ACK at the end of service call response transmission

From: David Howells
Date: Fri Sep 23 2016 - 11:15:43 EST


Don't send an IDLE ACK at the end of the transmission of the response to a
service call. The service end resends DATA packets until the client sends an
ACK that hard-acks all the send data. At that point, the call is complete.
