Subject: RE: [PATCH V4] net/mlx5: support ESP SPI match and RSS hash
Date: Wed, 11 May 2022 08:07:36 +0000	[thread overview]
Message-ID: <DM4PR12MB5389453C31243A0C76FA4D49DFC89@DM4PR12MB5389.namprd12.prod.outlook.com> (raw)

From: Raja Zidane
> In packets with ESP header, The Inner IP will be encrypted, and its fields cannot
> be used for RSS hashing. So, ESP packets can be hashed only by the outer IP
> layer.
> So, when using RSS on ESP packets, hashing may not be efficient, because the
> fields used by the hash functions are only the Outer IPs, causing all traffic
> belonging to all tunnels between a given pair of GWs to land on one core.
> Adding the SPI hash field can extend the spreading of IPSec packets.
> 
> support matching on ESP SPI.
> Support RSS on ESP header by hashing SPI field.
