Subject: [PATCH v2] dumpcap: add the mutiprocess fileprefix support.
Date: Mon, 12 Sep 2022 05:43:09 -0700 [thread overview]
Message-ID: <20220912124309.233363-1-arshdeep.kaur@intel.com> (raw)
In-Reply-To: <20220829074821.283063-1-arshdeep.kaur@intel.com>
New optional parameter "-m <fileprefix>" added.
It will update the mp_socket path for multiprocess communication.
Default : '/var/run/dpdk/rte/mp_socket'
Updated : '/var/run/dpdk/<file-prefix>/mp_socket'
Note: Give -m as first argument.
