Subject: [dpdk-dev] [PATCH] net/bnxt: fix mem zone free for Tx and Rx rings
Date: Fri, 24 Sep 2021 17:57:02 -0700	[thread overview]
Message-ID: <20210925005702.50971-1-ajit.khaparde@broadcom.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 1426 bytes --]

The device cleanup logic was freeing most of the ring related memory,
but was not freeing up the mem zone associated with the rings.
This patch fixes the issue.

Fixes: 2eb53b134aae ("net/bnxt: add initial Rx code")
Fixes: 6eb3cc2294fd ("net/bnxt: add initial Tx code")
Cc: stable@dpdk.org
