Subject: [dpdk-stable] [PATCH 18.11 5/5] net/bnxt: increase size of Rx CQ
Date: Tue, 1 Dec 2020 09:09:30 +0530 [thread overview]
Message-ID: <20201201033930.17869-6-kalesh-anakkur.purayil@broadcom.com> (raw)
In-Reply-To: <20201201033930.17869-1-kalesh-anakkur.purayil@broadcom.com>
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
[ upstream commit 45c6e1c66a4b5d7374e864502dc2fdb1ee71ceae ]
LRO aka TPA and jumbo frame support uses aggregation ring for placing
Rx buffers. These features can generate multiple Rx completions for a
single Rx packet. Increase size of Rx Completion Queue to handle TPA
and aggregation ring events.
Fixes: daef48efe5e5 ("net/bnxt: support set MTU")
