lagopus cannot start normally

[monstery]

Hi,
We have two CPU Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz on socket0 and socket1(total 24 cores), memory size is 48G and 28 Intel NICs on board, but we can not initiate lagopus.

The command is only to start 24 NICs but at last it will fail.
sudo /usr/sbin/lagopus -d -- -cfff -n 4 -- -pffffff

The following is our log.

Thank you for your report.
Due to he current limitation of DPDK and lagopus, the maximum number of ports is limited to 16 in Lagopus and 32 in DPDK.

Please change the source code as follows:
