Subject: [dpdk-dev] [PATCH] net/ixgbe: fix rss max rxtx queue num
Date: Tue, 31 Aug 2021 17:11:11 +0800	[thread overview]
Message-ID: <20210831091111.6879-1-chenqiming_huawei@163.com> (raw)

Through the local actual test, it is found that the maximum number of
RSS queues is 16, not 128. Check the chip manual, the register MRQE
has the following description: RSS only-Single set of RSS 16 queues.
It also coincides with the actual test value.

Fixes: abf7275bbaa2 ("ixgbe: move to drivers/net/")
Cc: stable@dpdk.org
