Subject: [PATCH 06/10] net/cnxk: add option to disable custom meta aura
Date: Fri, 17 May 2024 13:14:44 +0530 [thread overview]
Message-ID: <20240517074448.3146611-6-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20240517074448.3146611-1-ndabilpuram@marvell.com>
Add option to explicitly disable custom meta aura. Currently
custom meta aura is enabled automatically when inl_cpt_channel
is set i.e inline dev is masking CHAN field in IPsec rules.
Also decouple the custom meta aura feature from custom sa action
so that the custom sa action can independently be used.

+ Custom meta aura i.e 1:N meta aura is enabled for second pass traffic by default when
