rxrpc: Reduce the number of PING ACKs sent (fc943f67) · Commits · 戴 / test

We don't want to send a PING ACK for every new incoming call as that just adds to the network traffic. Instead, we send a PING ACK to the first three that we receive and then once per second thereafter. This could probably be made adjustable in future. Signed-off-by:
