In linux kernel since version 6.3 (release Date: 2023-04-23)  
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).
