Hello Freebsd-net,
Is `pkt-gen' (for netmap) supported on FreeBSD?
${SRCTOP}/tools/tools/netmap/pkt-gen.c is very old and could not be built
(I've checked stable/11, stable/12 and head).
${PORTS}/net/pkt-gen is not so old, but more than year old + patches
pkt-gen from github could be built on CURRENT, but can not finish
transmission:
236.545902 main_thread [2605] 0 pps (0 pkts 0 bps in 1031501 usec) 0.00

238.000017 sender_body [1687] pending tx tail 446 head 448 on ring 0
(forever)
and can not be used in benchmarking scripts...
Which one should I use? How could I be sure that transmission of given
number of packets will be finished in finite time no matter what? Is this
problem with tx queue really driver problem or netmap problem?
