From: Gaetan Rivet Date: Tue, 18 Apr 2017 12:17:41 +0000 (+0200) Subject: app/testpmd: request link status interrupt X-Git-Tag: spdx-start~3435 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8ea656f8c300175ac84f3cbe1117f5ef11ffc4eb;p=dpdk.git app/testpmd: request link status interrupt 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.
