Subject: bus/dpaa: enhance checks for bus and device detection
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a047154e8bff20af1ae3de1cb77b4c376790672d;p=dpdk.git

bus/dpaa: enhance checks for bus and device detection

1. It is not a error if no network device available. One can
only use crypto device
2. Improve logging for failure in detecting the bus
