Subject: [PATCH net-next ct-offload v3 10/15] net/mlx5: E-Switch, Support getting chain mapping
Date: Wed, 11 Mar 2020 16:33:53 +0200	[thread overview]
Message-ID: <1583937238-21511-11-git-send-email-paulb@mellanox.com> (raw)
In-Reply-To: <1583937238-21511-1-git-send-email-paulb@mellanox.com>

Currently, we write chain register mapping on miss from the the last
prio of a chain. It is used to restore the chain in software.

To support re-using the chain register mapping from global tables (such
as CT tuple table) misses, export the chain mapping.
