Subject: [PATCH 5/8] net/nfp: add support for VLAN strip V2
Date: Mon, 28 Nov 2022 14:53:56 +0800	[thread overview]
Message-ID: <20221128065359.12737-6-chaoyong.he@corigine.com> (raw)
In-Reply-To: <20221128065359.12737-1-chaoyong.he@corigine.com>

From: Peng Zhang <peng.zhang@corigine.com>

The VLAN information can be stored in the descriptor or in the metadata.
Add a new VLAN strip V2 bit to distinguish them. When VLAN strip is set,
the vlan information is stored in the descriptor. When VLAN strip V2 is
set, it is stored in the metadata.
