Subject: [net-next PATCH v10 6/8] cn10k-ipsec: Process outbound ipsec crypto offload
Prepare and submit crypto hardware (CPT) instruction for
outbound ipsec crypto offload. The CPT instruction have
authentication offset, IV offset and encapsulation offset
in input packet. Also provide SA context pointer which have
details about algo, keys, salt etc. Crypto hardware encrypt,
authenticate and provide the ESP packet to networking hardware.
Signed-off-by: Bharat Bhushan <bbhushan2@...vell.com>
---
v9->v10:
- Removed unlikely() in data-patch and used static_branch when at least
a SA is configured.
v3->v4:
- Few error messages in datapath removed and some moved
under netif_msg_tx_err().
- Fixed codespell error as per comment from Simon Horman
