[dpdk-dev] [PATCH 04/16] [RFC] [VFIO] Make igb_uio compilation optional

[Burakov, Anatoly]

Currently, igb_uio is always compiled. Since no Linux distribution
would want to include igb_uio by default or even with DPDK, we need
to make sure that igb_uio compilation can be optional (i.e. some
distributions could ship DPDK with VFIO support only).
