If CONFIG_AF_RXRPC_DEBUG_RX_DELAY=y, then a delay is injected between packets and errors being received and them being made available to the processing code, thereby allowing the RTT to be artificially increased.

Say Y or M here to include support for RxRPC session sockets (just
|
|
the transport part, not the presentation part: (un)marshalling is
|
|
left to the application).
|
|
|
|
These are used for AFS kernel filesystem and userspace utilities.
|
|
|
|
This module at the moment only supports client operations and is
|
|
currently incomplete.

Say Y here to inject a delay into packet reception, allowing an

extended RTT time to be modelled. The delay can be configured using

/proc/sys/net/rxrpc/rxrpc_inject_rx_delay, setting a number of

milliseconds up to 0.5s (note that the granularity is actually in

jiffies).
