+ pkt-gen -f rx now remains active even when traffic stops Previous behaviour (exit after 1 second of silence) can be restored with the -W option + the -X option does a hexdump of the content of a packet (both tx and rx). This can be useful to check what goes in and out. + the -I option instructs the sender to use indirect buffers (not really useful other than to test the kernel module in the VALE switch) |
