Subject: [dpdk-dev] [PATCH 1/2] net/ark: remove queue offset based on port id
Date: Fri, 19 Jul 2019 09:07:42 -0400	[thread overview]
Message-ID: <1563541663-10797-1-git-send-email-ed.czeck@atomicrules.com> (raw)
In-Reply-To: <1563312861-26219-1-git-send-email-ed.czeck@atomicrules.com>

Queue index was incorrectly incremented with port, which
caused swizzling of packet placement among queues. This manifested
when the number of configured ports was >1 and < nb_queues.

Fixes: c33d45af3633 ("net/ark: add Tx initial version")
Cc: stable@dpdk.org
