Subject: [PATCH AUTOSEL 5.12 105/116] net: ethernet: mtk_eth_soc: fix RX VLAN offload
Date: Wed, 5 May 2021 12:31:13 -0400 [thread overview]
Message-ID: <20210505163125.3460440-105-sashal@kernel.org> (raw)
In-Reply-To: <20210505163125.3460440-1-sashal@kernel.org>
From: Felix Fietkau <nbd@nbd.name>
[ Upstream commit 3f57d8c40fea9b20543cab4da12f4680d2ef182c ]
The VLAN ID in the rx descriptor is only valid if the RX_DMA_VTAG bit is
set. Fixes frames wrongly marked with VLAN tags.
