Subject: [net-next 15/15] net/mlx5e: Support IPsec upper TCP protocol selector
Date: Tue, 22 Aug 2023 22:10:12 -0700	[thread overview]
Message-ID: <20230823051012.162483-16-saeed@kernel.org> (raw)
In-Reply-To: <20230823051012.162483-1-saeed@kernel.org>

From: Leon Romanovsky <leonro@nvidia.com>

Support TCP as protocol selector for policy and state in IPsec
packet offload mode.

Example of state configuration is as follows:
  ip xfrm state add src 192.168.25.3 dst 192.168.25.1 \
	proto esp spi 1001 reqid 10001 aead 'rfc4106(gcm(aes))' \
	0x54a7588d36873b031e4bd46301be5a86b3a53879 128 mode transport \
	offload packet dev re0 dir in sel src 192.168.25.3 dst 192.168.25.1 \
	proto tcp dport 9003
