Subject: [PATCH AUTOSEL 5.16 13/19] net/mlx5_vdpa: Offer VIRTIO_NET_F_MTU when setting MTU
Date: Sat, 22 Jan 2022 19:11:06 -0500 [thread overview]
Message-ID: <20220123001113.2460140-13-sashal@kernel.org> (raw)
In-Reply-To: <20220123001113.2460140-1-sashal@kernel.org>
From: Eli Cohen <elic@nvidia.com>
[ Upstream commit 60af39c1f4cc92cc2785ef745c0c97558134d539 ]
Make sure to offer VIRTIO_NET_F_MTU since we configure the MTU based on
what was queried from the device.
This allows the virtio driver to allocate large enough buffers based on
the reported MTU.
