From: Tomasz Duszynski Date: Tue, 5 Dec 2017 09:39:19 +0000 (+0100) Subject: net/mrvl: check if ppio is initialized X-Git-Tag: spdx-start~603 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c0511a8f741fdc475cf29f714b19c04589207e67;p=dpdk.git net/mrvl: check if ppio is initialized Uninitialized ppio cannot be passed to MUSDK library routines as application will crash. Fix this by first checking whether ppio has been initialized.
