Subject: [dpdk-dev] [PATCH v2 2/2] ipc: fix timeout not properly handled in async
Date: Fri, 20 Apr 2018 15:20:12 +0000 [thread overview]
Message-ID: <1524237612-130629-3-git-send-email-jianfeng.tan@intel.com> (raw)
In-Reply-To: <1524237612-130629-1-git-send-email-jianfeng.tan@intel.com>
In original implementation, timeout event for an async request
will be ignored. As a result, an async request will never
trigger the action if it cannot receive any reply any more.
We fix this by counting timeout as a processed reply.
Fixes: f05e26051c15 ("eal: add IPC asynchronous request")
