Subject: [PATCH 2/5] net/virtio-user: get link duplex and speed
Date: Mon, 7 Oct 2024 20:34:00 +0530	[thread overview]
Message-ID: <20241007150403.1680983-2-skoteshwar@marvell.com> (raw)
In-Reply-To: <20241007150403.1680983-1-skoteshwar@marvell.com>

From: Satha Rao <skoteshwar@marvell.com>

This patch extends the virtio_user_read_dev_config API to retrieve link
speed and duplex settings if the device features support
VIRTIO_NET_F_SPEED_DUPLEX.
