Subject: [Intel-wired-lan] [PATCH net-next v5 05/11] igc: Optimze TX buffer sizes for TSN
Date: Thu, 19 May 2022 18:15:32 -0700 [thread overview]
Message-ID: <20220520011538.1098888-6-vinicius.gomes@intel.com> (raw)
In-Reply-To: <20220520011538.1098888-1-vinicius.gomes@intel.com>
There are 64KB buffer space shared for TX and RX (including the BMC).
We were only reserving 22KB for TX, increase each TX buffer (per
queue) by 2KB, the total is now 30KB for TX.
Signed-off-by: Vinicius Costa Gomes <vinicius.gomes@intel.com>
