Subject: [dpdk-dev] [PATCH 2/2] net/netvsc: fix ethdev get_supported_ptypes
Date: Mon, 23 Nov 2020 14:19:18 -0800
Message-ID: <20201123221918.20825-3-stephen@networkplumber.org> (raw)
In-Reply-To: <20201123221918.20825-1-stephen@networkplumber.org>

When doing rte_eth_dev_get_supported_ptypes on netvsc device
the values reported are incorrect if VF is not present.

If no VF is present the device uses rte_net_get_ptype()
which can return a wide range of values. Use the same table
as TAP device in that case.
