[PATCH v10 08/10] virtio-net: add support for configure interrupt |
Date: |
Fri, 5 Nov 2021 00:48:25 +0800 |
Add functions to support configure interrupt in virtio_net
The functions are config_pending and config_mask, while
this input idx is VIRTIO_CONFIG_IRQ_IDX will check the
function of configure interrupt.
