Subject: [net-next PATCH v4 07/13] net: netcp: ethss: map vlan priorities to zero flow
Date: Tue, 17 Apr 2018 17:30:36 -0400	[thread overview]
Message-ID: <1524000642-23944-8-git-send-email-m-karicheri2@ti.com> (raw)
In-Reply-To: <1524000642-23944-1-git-send-email-m-karicheri2@ti.com>

The driver currently support only vlan priority zero. So map the
vlan priorities to zero flow in hardware.
