Subject: [dpdk-dev] [PATCH 09/25] net/bnxt: fix the function id used in the flow flush
Date: Thu, 10 Sep 2020 18:55:47 -0700
Message-ID: <20200911015603.88359-10-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20200911015603.88359-1-ajit.khaparde@broadcom.com>

From: Kishore Padmanabha <kishore.padmanabha@broadcom.com>

The function id being used in the flush is incorrect, fixed the
flush of the flows.

Fixes: 74bcfc062489 ("net/bnxt: add session and function flow flush")
