Subject: [net PATCH 2/2] octeontx2-af: fix lbk link credits on cn10k
Date: Thu, 8 Jun 2023 17:12:01 +0530 [thread overview]
Message-ID: <20230608114201.31112-3-naveenm@marvell.com> (raw)
In-Reply-To: <20230608114201.31112-1-naveenm@marvell.com>
From: Nithin Dabilpuram <ndabilpuram@marvell.com>
Fix LBK link credits on CN10K to be same as CN9K i.e
16 * MAX_LBK_DATA_RATE instead of current scheme of
calculation based on LBK buf length / FIFO size.
Fixes: 6e54e1c5399a ("octeontx2-af: cn10K: Add MTU configuration")
