Subject: [dpdk-dev] [PATCH v6 2/2] app/testpmd: add send scheduling test capability
Date: Thu,  9 Jul 2020 12:36:56 +0000
Message-ID: <1594298216-3746-2-git-send-email-viacheslavo@mellanox.com> (raw)
In-Reply-To: <1594298216-3746-1-git-send-email-viacheslavo@mellanox.com>

This commit adds testpmd capability to provide timestamps on the packets
being sent in the txonly mode. This includes:

 - SEND_ON_TIMESTAMP support
   new device Tx offload capability support added, example:

     testpmd> port config 0 tx_offload send_on_timestamp on

 - set txtimes, registers field and flag, example:

     testpmd> set txtimes 1000000,0

   This command enables the packet send scheduling on timestamps if
   the first parameter is not zero, generic format:

     testpmd> set txtimes (inter),(intra)

   where:

     inter - is the delay between the bursts in the device clock units.
     intra - is the delay between the packets within the burst specified
	     in the device clock units

     As the result the bursts of packet will be transmitted with
     specific delay between the packets within the burst and specific
     delay between the bursts. The rte_eth_get_clock() is supposed to be
     engaged to get the current device clock value and provide
     the reference for the timestamps.

 - show txtimes, displays the timing settings
 - txonly burst time pattern
