Subject: [dpdk-stable] [PATCH 1/4] net/txgbe: fix RSS in double VALN
Date: Sun, 25 Apr 2021 16:03:44 +0800
Message-ID: <20210425080347.20376-2-jiawenwu@trustnetic.com> (raw)
In-Reply-To: <20210425080347.20376-1-jiawenwu@trustnetic.com>

Regard QINQ as one case of extend VLAN, and always enable QINQ mode when
double VLAN is set, to avoid RSS does not work for QINQ packets.

Fixes: 220b0e49bc47 ("net/txgbe: support VLAN")
Cc: stable@dpdk.org
