[dpdk-dev] [PATCH] vfio-pci: Fixing type used to unsigned long

[Alejandro.Lucero]

From: "Alejandro.Lucero" <alejandro.luc...@netronome.com>

VFIO kernel driver and mmap system call expect offset and size being 64 bits.

Due to this bug BAR index info given to the VFIO driver is always 0 when 
checking validity of resources mapping.
