Subject: [dpdk-dev] [PATCH 2/5] lib/librte_pdump: add new library for packet capturing support
Date: Fri, 6 May 2016 11:55:36 +0100 [thread overview]
Message-ID: <1462532139-17848-3-git-send-email-reshma.pattan@intel.com> (raw)
In-Reply-To: <1462532139-17848-1-git-send-email-reshma.pattan@intel.com>
Added new library for packet capturing support.
Added public api rte_pdump_init, applications should call
this as part of their application setup to have packet
capturing framework ready.
Added public api rte_pdump_uninit to un initialize the packet
capturing framework.
Added public apis rte_pdump_enable and rte_pdump_disable to
enable and disable packet capturing on specific port and queue.
Added public apis rte_pdump_enable_by_deviceid and
rte_pdump_disable_by_deviceid to enable and disable packet
capturing on a specific device (pci address or name) and queue.
