Subject: [dpdk-dev] [PATCH 11/12] testpmd: support TSO in csum forward engine
Date: Mon, 10 Nov 2014 16:59:25 +0100	[thread overview]
Message-ID: <1415635166-1364-12-git-send-email-olivier.matz@6wind.com> (raw)
In-Reply-To: <1415635166-1364-1-git-send-email-olivier.matz@6wind.com>

Add two new commands in testpmd:

- tso set <segsize> <portid>
- tso show <portid>

These commands can be used enable TSO when transmitting TCP packets in
the csum forward engine. Ex:

  set fwd csum
  tx_checksum set ip hw 0
  tso set 800 0
  start
