David Howells 4790963ef4 rxrpc: Fix decision on when to generate an IDLE ACK ... [ Upstream commit 9a3dedcf18096e8f7f22b8777d78c4acfdea1651 ] Fix the decision on when to generate an IDLE ACK by keeping a count of the number of packets we've received, but not yet soft-ACK'd, and the number of packets we've processed, but not yet hard-ACK'd, rather than trying to keep track of which DATA sequence numbers correspond to those points. We then generate an ACK when either counter exceeds 2. The counters are both cleared when we transcribe the information into any sort of ACK packet for transmission. IDLE and DELAY ACKs are skipped if both counters are 0 (ie. no change).
