From da802961832f9852886304290135457519815497 Mon Sep 17 00:00:00 2001 From: Xuan Zhuo Date: Mon, 1 Aug 2022 14:38:21 +0800 Subject: virtio: record the maximum queue num supported by the device. virtio-net can display the maximum (supported by hardware) ring size in ethtool -g eth0. When the subsequent patch implements vring reset, it can judge whether the ring size passed by the driver is legal based on this.
