[dpdk-dev] [PATCH v2] cfgfile: fix unitialised buffer

[Daniel Mrzyglod]

Nature of the problem was not initialised buffer[256], there were probability
that operation system will provide previously used memory and on special condition
there were probability that string operations will work on random data that
could provide unexpected program behaviour.
