Subject: [PATCH v4 net-next 13/13] octeontx2-af: Delete NIX_RXVLAN_ALLOC mailbox message
Date:   Sun, 15 Nov 2020 01:23:03 +0530
Message-ID: <20201114195303.25967-14-naveenm@marvell.com>
In-Reply-To: <20201114195303.25967-1-naveenm@marvell.com>
References: <20201114195303.25967-1-naveenm@marvell.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

From: Subbaraya Sundeep <sbhatta@marvell.com>

Since mailbox message for installing flows is in place,
remove the RXVLAN_ALLOC mbox message which is redundant.
