Subject: [dpdk-stable] [PATCH 18.08] net/softnic: fix undefined dev info fields
Date: Thu, 29 Nov 2018 14:52:26 +0000 [thread overview]
Message-ID: <20181129145226.58362-1-jasvinder.singh@intel.com> (raw)
The memcpy operation overwrites the device info fields set
by ethdev API and leaves the device field undefined.
Thus, replaces memcpy by only updating the required fields
at the driver layer.
error log: testpmd> show port info 1
**** Infos for port 1 ****
MAC address: 00:00:00:00:00:00
Device name: net_softnic0
Segmentation fault.
port_infos_display (port_id=1) at /dpdk/app/test-pmd/config.c:418
if (dev_info.device->devargs && dev_info.device->devargs->args)
Fixes: cc6d421574fe ("net/softnic: add softnic PMD")
