Subject: [dpdk-dev] net/i40e: fix intr callback unregister by adding retry
Date: Sat, 10 Mar 2018 14:50:43 +0800 [thread overview]
Message-ID: <1520664643-13808-1-git-send-email-wangyunjian@huawei.com> (raw)
From: Yunjian Wang <wangyunjian@huawei.com>
The nic's interrupt source has some active callbacks, when
the port hotplug. Add a retry to give more port's a chance
to uninit before returning an error.
Fixes: d42aaf30008b ("i40e: support port hotplug")
