[dpdk-dev] [PATCH] cfgfile: Fix for Reading Files on nfs filesystem.

[Daniel Mrzyglod]

The problem occure when we have config files on NFS filesystem.
Solution with minimal change to library is to add buffer for I/O operations.
Without buffering there is  3-10% of faulty Reading from NFS.

The problem seems to be only NFS filesystem.
