Hi Shreyansh,
When initializing DPDK on x86, we get those warnings:
dpaax: Unable to glob device-tree memory node: (/proc/device-tree/memory[@0-9]*/reg)(3)
dpaax: PA->VA translation not available;
dpaax: Expect performance impact.
Is it possible to avoid running dpaax init when not available?

I will send a fix. I think only option I have is to reduce the level of
the messages. This message essentially states that as dpaax bus was not
found, the library won't work.
I will send a patch.
