# Read packets using DPDK input interface and 1 DPDK queue, enable plugins for basic statistics, http and tls, output to IPFIX on a local machine
# DPDK EAL parameters are passed in `e, eal` parameters
# DPDK plugin configuration has to be specified in the first input interface, others dpdk interfaces inherit configuration from the first interface
For example: `./ipfixprobe -i "dpdk;p=0,q=1,e=-c 0x1 -a <[domain:]bus:devid.func>" -p http "-p" bstats -p tls -o "ipfix;h=127.0.0.1"`
# DPDK plugin configuration has to be specified in the first input interface.
# The following `dpdk` interfaces are given without parameters; their configuration is inherited from the first one.
# Example for the queue of 3 DPDK input plugins (`q=3`):
`./ipfixprobe -i "dpdk;p=0,q=3,e=-c 0x1 -a <[domain:]bus:devid.func>" -i dpdk -i dpdk -p http "-p" bstats -p tls -o "ipfix;h=127.0.0.1"`
