From: Natalie Samsonov Date: Tue, 25 Sep 2018 07:04:57 +0000 (+0200) Subject: net/mvpp2: initialize ppio only once X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5997b0a827619b085852a00cb78af31ba4edac7c;p=dpdk.git net/mvpp2: initialize ppio only once This changes stop/start/configure behavior due to issue in MUSDK library itself. From now on, ppio can be reconfigured only after interface is closed.
