Subject: [dpdk-dev] [PATCH v3 1/3] ethdev: add actions to modify TCP header fields
Date: Wed, 10 Apr 2019 14:26:38 +0300
Message-ID: <0235680ea84ba74d3ecebb62bf5af19559c5170e.1554894982.git.dekelp@mellanox.com> (raw)
In-Reply-To: <cover.1554894982.git.dekelp@mellanox.com>

Add actions:
- INC_TCP_SEQ - Increase sequence number in the outermost TCP header.
- DEC_TCP_SEQ - Decrease sequence number in the outermost TCP header.
- INC_TCP_ACK - Increase acknowledgment number in the outermost TCP
		header.
- DEC_TCP_ACK - Decrease acknowledgment number in the outermost TCP
		header.

Original work by Xiaoyu Min.
