Subject: [dpdk-dev] [PATCH v8 1/3] ethdev: add actions to modify TCP header fields
Date: Sun, 30 Jun 2019 10:59:08 +0300	[thread overview]
Message-ID: <8b43b7e77d467429b45cb86eb09e218d721dd0de.1561872899.git.dekelp@mellanox.com> (raw)
In-Reply-To: <cover.1561872899.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.

This patch introduces a new approach, using a simple integer instead
of using an action-specific structure for each of these actions.
This approach can be later applied to modify existing actions which
require only a single integer.
