[dpdk-dev] [PATCH v5 13/15] examples/ipsec-secgw: make number of buffers dynamic

Thu Feb 27 17:18:35 CET 2020
Make number of buffers in a pool nb_mbuf_in_pool dependent on number
of ports, cores and crypto queues. Add command line option -s which
when used overrides dynamic calculation of number of buffers in a pool.
