Subject: [PATCH 04/17] net/bnxt: fix Rxq configure
Date: Wed, 27 Apr 2022 20:28:08 +0530 [thread overview]
Message-ID: <20220427145821.5987-5-kalesh-anakkur.purayil@broadcom.com> (raw)
In-Reply-To: <20220427145821.5987-1-kalesh-anakkur.purayil@broadcom.com>
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
We are currently not handling RX/RSS modes correctly.
After launching testpmd with multiple RXQs, if the user tries to set
the number of RXQs to 1, driver is not updating the "hash_type"
and "hash_mode" values of the VNICs. As a result, driver issues
bnxt_vnic_rss_configure() unnecessarily and the FW command fails.
Fixed bnxt_mq_rx_configure() to update VNIC RSS fields unconditionally.
Fixes: 4191bc8f79a8 ("net/bnxt: handle multi queue mode properly")
