Subject: [dpdk-dev] [PATCH 2/4] bus/vmbus: remove vmbus_send_interrupt
Date: Mon, 10 Aug 2020 19:33:12 -0700	[thread overview]
Message-ID: <1597113194-90208-2-git-send-email-longli@linuxonhyperv.com> (raw)
In-Reply-To: <1597113194-90208-1-git-send-email-longli@linuxonhyperv.com>

From: Long Li <longli@microsoft.com>

netvsc is a high speed VMBus device that uses monitor bit to signal the
host. It's not necessary to send interrupts via INT bit.
