Subject: [dpdk-stable] [PATCH v2] net/ice: fix queue config in DCF
Date: Tue, 24 Aug 2021 15:13:17 +0000 [thread overview]
Message-ID: <20210824151317.129271-1-jie1x.wang@intel.com> (raw)
In-Reply-To: <20210820135458.317056-1-jie1x.wang@intel.com>
When DCF configures rx_queues, it may cause the pointer of
rx_queues to go out of bounds.
This patch expands the scope of the judgment condition to
fix this issue.
Fixes: 4b0d391f0eab ("net/ice: add queue config in DCF")

v2: assign values to rxq.vsi_id and rxq.queue_id, ensure rxq.vsi_id
is equal to txq.vsi_id and rxq.queue_id is equal to txq.queue_id.
