I am trying to use the pktgen to generate the test pkt to fullfill a task I am using the testing script from https://github.com/torvalds/linux/tree/master/samples/pktgen using the command like this bash pktgen_sample02_multiqueue.sh -i eth1 -d <ip> -s 64 -m <mac> -c 10 -p 40000-40003 -n 0 -t 2 -x and it's working on centos7.9 But I want to set the pkt ttl to 255(max ttl) and I using the echo "ttl 255 " > /proc/net/pktgen/eth1@0 and show's the error -bash: echo: write error: Invalid argument

does anyone can show me if pktgen can support to set the ttl ?
