Subject: virtio-net: why not always to set avail->flags to VRING_AVAIL_F_NO_INTERRUPT
Date: Wed, 3 Jun 2015 14:32:39 +0800	[thread overview]
Message-ID: <556E9F87.7030202@huawei.com> (raw)

Hi,

I'm a newbie and have a question about vring_new_virtqueue function.

Why we set avail->flags to VRING_AVAIL_F_NO_INTERRUPT when no callbacks?
I think we should set avail->flags to VRING_AVAIL_F_NO_INTERRUPT even if no callbacks.
