Subject: [dpdk-dev] [PATCH v2 4/5] app/testpmd: request link status interrupt
Date: Tue, 18 Apr 2017 14:17:41 +0200 [thread overview]
Message-ID: <83bfe3fd6dc1f7696049bf8d8d1ef20370c92242.1492517222.git.gaetan.rivet@6wind.com> (raw)
In-Reply-To: <cover.1492517222.git.gaetan.rivet@6wind.com>
In-Reply-To: <cover.1492517222.git.gaetan.rivet@6wind.com>
For drivers supporting the LSC event, enable it.
This allows to test LSC event support.
Add the --no-lsc-interrupt parameter to explicitly disable the link status
change interrupt.
