Subject: [PATCH AUTOSEL 6.1 32/35] octeontx2-af: update cpt lf alloc mailbox
Date: Tue, 24 Jan 2023 08:41:28 -0500	[thread overview]
Message-ID: <20230124134131.637036-32-sashal@kernel.org> (raw)
In-Reply-To: <20230124134131.637036-1-sashal@kernel.org>

From: Srujana Challa <schalla@marvell.com>

[ Upstream commit c0688ec002a451d04a51d43b849765c5ce6cb36f ]

The CN10K CPT coprocessor contains a context processor
to accelerate updates to the IPsec security association
contexts. The context processor contains a context cache.
This patch updates CPT LF ALLOC mailbox to config ctx_ilen
requested by VFs. CPT_LF_ALLOC:ctx_ilen is the size of
initial context fetch.
