Subject: [dpdk-dev] [PATCH] net/ixgbe: fix crash when on remove
Date: Wed, 13 Feb 2019 10:48:52 +0800 [thread overview]
Message-ID: <1550026132-9244-1-git-send-email-wangyunjian@huawei.com> (raw)
From: Yunjian Wang <wangyunjian@huawei.com>
The nic's interrupt source has some active handler, when the
port remove. We should cancel the delay handler before remove
dev to prevent executing the delay handler.
Call Trace:
