Subject: [dpdk-stable] [PATCH 1/1] net/bnxt: fix handling of null flow mask
Date: Thu, 18 Mar 2021 15:52:51 -0400 [thread overview]
Message-ID: <20210318195251.683450-1-lance.richardson@broadcom.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 3357 bytes --]
When the mask field of an rte_flow pattern item is NULL,
the default mask for that item type should be used.
Fixes: 5ef3b79fdfe6 ("net/bnxt: support flow filter ops")
