.SH NAME
queuelat \- Queue latency test program
.SH SYNOPSIS
.B queuelat
.RI "[\-h] [\-m " max-queue-len "] [\-c " cycles-per-packet "] [\-p " mpps "] [\-f " tsc-freq "] [\-t " timeout "] \

.SH DESCRIPTION
queuelat simulates a network queue checking for latency
violations in packet processing.

.SH OPTIONS
A summary of options is included below.
.TP
.B \-h
Show help
.br
.TP
.B \-m max-queue-len
Maximum allowed latency, in nanoseconds. If latency to process
.br
any packet exceeds this value, the program quits,
writing
.br
a message to the trace buffer.
.TP
.B \-c cycles-per-packet
Estimated number of cycles it takes to process one packet.
.br
This value should come from the envisioned packet
.br
forwarding application being simulated.
.TP
.B \-p mpps
Million packets per second that arrive for processing.
.TP
.B \-f tsc-freq-mhz
TSC frequency in MHz.
.TP
.B \-t timeout
Timeout in seconds to quit the program.
