Subject: [dpdk-dev] [PATCH v6 15/23] event/dlb: add port unlink and port unlinks in progress
Date: Fri, 23 Oct 2020 13:32:24 -0500	[thread overview]
Message-ID: <1603477952-583-16-git-send-email-timothy.mcdaniel@intel.com> (raw)
In-Reply-To: <1603477952-583-1-git-send-email-timothy.mcdaniel@intel.com>

Add supports for the port unlink(s) eventdev entry points.
The unlink operation is an asynchronous operation executed by
a control thread, and the unlinks-in-progress function reads
a counter shared with the control thread. Port QE and memzone
memory is freed here.
