Subject: [dpdk-dev] [PATCH 2/2] net/tap: fix tap interrupt vector array size
Date: Thu, 22 Apr 2021 19:27:14 +0800	[thread overview]
Message-ID: <1619090834-14643-3-git-send-email-humin29@huawei.com> (raw)
In-Reply-To: <1619090834-14643-1-git-send-email-humin29@huawei.com>

From: Chengchang Tang <tangchengchang@huawei.com>

The size of the current interrupt vector array is fixed to an integer.

This patch will create an interrupt vector array based on the number
of rxqs.

Fixes: 4870a8cdd968 ("net/tap: support Rx interrupt")
